Changes from v1:
The patch series supports WDT, SDMC, SMC, SCU, SLI and INTC for AST2700 SoC.
Changes from v2:
- replace is_aarch64 with is_bus64bit for sdmc patch review.
- fix incorrect dram size for AST2700
Changes from v3:
- Add AST2700 Evaluation board in ASPEED document
- Add avocado test cases for AST2700 Evaluation board
- Fix reviewers review issues and add reviewers suggestions
- Implement INTC model GICINT 128 to GICINT136 for AST2700
Test steps:
1. Download the latest openbmc image for AST2700 from AspeedTech-BMC/openbmc
repository, https://github.com/AspeedTech-BMC/openbmc/releases/tag/v09.01
link: https://github.com/AspeedTech-BMC/openbmc/releases/download/v09.01/ast2700-default-obmc.tar.gz
2. untar ast2700-default-obmc.tar.gz
```
tar -xf ast2700-default-obmc.tar.gz
```
3. Run and the contents of scripts as following
IMGDIR=ast2700-default
UBOOT_SIZE=$(stat --format=%s -L ${IMGDIR}/u-boot-nodtb.bin)
UBOOT_DTB_ADDR=$((0x400000000 + ${UBOOT_SIZE}))

AST2700 wdt controller is similiar to AST2600's wdt, but
the AST2700 has 8 watchdogs, and they each have 0x80 of registers.
Introduce ast2700 object class and increase the number of regs(offset) of
ast2700 model.

The SDRAM memory controller(DRAMC) controls the access to external
DDR4 and DDR5 SDRAM and power up to DDR4 and DDR5 PHY.
The DRAM memory controller of AST2700 is not backward compatible
to previous chips such AST2600, AST2500 and AST2400.
Max memory is now 8GiB on the AST2700. Introduce new
aspeed_2700_sdmc and class with read/write operation and
reset handlers.
Define DRAMC necessary protected registers and
unprotected registers for AST2700 and increase
the register set to 0x1000.
Add unlocked property to change controller protected status.

DMA length is from 1 byte to 32MB for AST2600 and AST10x0
and DMA length is from 4 bytes to 32MB for AST2500.
In other words, if "R_DMA_LEN" is 0, it should move at least 1 byte
data for AST2600 and AST10x0 and 4 bytes data for AST2500.
To support all ASPEED SOCs, adds dma_start_length parameter to store
the start length, add helper routines function to compute the dma length
and update DMA_LENGTH mask to "1FFFFFF" to fix dma moving
incorrect data length issue.
Currently, only supports dma length 4 bytes aligned.

AST2700 support the maximum dram size is 8GiB
and has a "DMA DRAM Side Address High Part(0x7C)"
register to support 64 bits dma dram address.
Add helper routines functions to compute the dma dram
address, new features and update trace-event
to support 64 bits dram address.

AST2700 fmc/spi controller's address decoding unit is 64KB
and only bits [31:16] are used for decoding. Introduce seg_to_reg
and reg_to_seg handlers for ast2700 fmc/spi controller.
In addition, adds ast2700 fmc, spi0, spi1, and spi2 class init handler.

AST2700 have two SCU controllers which are SCU and SCUIO.
Both SCU and SCUIO registers are not compatible previous SOCs
, introduces new registers and adds ast2700 scu, sucio class init handler.
The pclk divider selection of SCUIO is defined in SCUIO280[20:18] and
the pclk divider selection of SCU is defined in SCU280[25:23].
Both of them are not compatible AST2600 SOCs, adds a get_apb_freq function
and trace-event for AST2700 SCU and SCUIO.

AST2700 interrupt controller(INTC) provides hardware interrupt interfaces
to interrupt of processors PSP, SSP and TSP. In INTC, each interrupt of
INT 128 to INT136 combines 32 interrupts.
Introduce a new aspeed_intc class with instance_init and realize handlers.
So far, this model only supports GICINT128 to GICINT136.
It creates 9 GICINT or-gates to connect 32 interrupts sources
from GICINT128 to GICINT136 as IRQ GPIO-OUTPUT pins.
Then, this model registers IRQ handler with its IRQ GPIO-INPUT pins which
connect to GICINT or-gates. And creates 9 GICINT IRQ GPIO-OUTPUT pins which
connect to GIC device with GIC IRQ 128 to 136.
If one interrupt source from GICINT128 to GICINT136
set irq, the OR-GATE irq callback function is called and set irq to INTC by
OR-GATE GPIO-OUTPUT pins. Then, the INTC irq callback function is called and
set irq to GIC by its GICINT IRQ GPIO-OUTPUT pins. Finally, the GIC irq
callback function is called and set irq to CPUs and
CPUs execute Interrupt Service Routine (ISR).

Initial definitions for a simple machine using an AST2700 SOC (Cortex-a35 CPU).
AST2700 SOC and its interrupt controller are too complex to handle
in the common Aspeed SoC framework. We introduce a new ast2700
class with instance_init and realize handlers.
AST2700 is a 64 bits quad core cpus and support 8 watchdog.
Update maximum ASPEED_CPUS_NUM to 4 and ASPEED_WDTS_NUM to 8.
In addition, update AspeedSocState to support scuio, sli, sliio and intc.
Add TYPE_ASPEED27X0_SOC machine type.
The SDMC controller is unlocked at SPL stage.
At present, only supports to emulate booting
start from u-boot stage. Set SDMC controller
unlocked by default.
In INTC, each interrupt of INT 128 to INT 136 combines 32 interrupts.
It connect GICINT IRQ GPIO-OUTPUT pins to GIC device with irq 128 to 136.
And, if a device irq is 128 to 136, its irq GPIO-OUTPUT pin is connected to
GICINT or-gates instead of GIC device.

AST2700 CPU is ARM Cortex-A35 which is 64 bits.
Add TARGET_AARCH64 to build this machine.
According to the design of ast2700, it has a bootmcu(riscv-32) which
is used for executing SPL.
Then, CPUs(cortex-a35) execute u-boot, kernel and rofs.
Currently, qemu not support emulate two CPU architectures
at the same machine. Therefore, qemu will only support
to emulate CPU(cortex-a35) side for ast2700

AST2700 dram size calculation is not back compatible AST2600.
According to the DDR capacity hardware behavior,
if users write the data to address which is beyond the ram size,
it would write the data to address 0.
For example:
a. sdram base address "0x4 00000000"
b. sdram size is 1 GiB
The available address range is from "0x4 00000000" to "0x4 40000000".
If users write 0xdeadbeef to address "0x6 00000000",
the value of DRAM address 0 (base address 0x4 00000000) should be 0xdeadbeef.
Add aspeed_soc_ast2700_dram_init to calculate the dram size and add
memory I/O whose address range is from max_ram_size - ram_size to max_ram_size
and its read/write handler to emulate DDR capacity hardware behavior.

Add a test case to test Aspeed OpenBMC SDK v09.01 on AST2700 board.
It loads u-boot-nodtb.bin, u-boot.dtb, tfa and optee-os
images to dram first which base address is 0x400000000.
Then, boot and launch 4 cpu cores.
```
qemu-system-aarch64 -machine ast2700-evb
-device loader,force-raw=on,addr=0x400000000,file=workdir/u-boot-nodtb.bin \
-device loader,force-raw=on,addr=uboot_dtb_load_addr,file=u-boot.dtb\
-device loader,force-raw=on,addr=0x430000000,file=workdir/bl31.bin\
-device loader,force-raw=on,addr=0x430080000,file=workdir/optee/tee-raw.bin\
-device loader,cpu-num=0,addr=0x430000000 \
-device loader,cpu-num=1,addr=0x430000000 \
-device loader,cpu-num=2,addr=0x430000000 \
-device loader,cpu-num=3,addr=0x430000000 \
-smp 4 \
-drive file=workdir/image-bmc,format=raw,if=mtd
```

Why do you truncate the address again ? It should already be done with

The reason is that our firmware set the real address in SMC registers.
For example: If users want to move data from flash to the DRAM at address 0,
It set R_DMA_DRAM_ADDR_HIGH 4 and R_DMA_DRAM_ADDR 0 because the
dram base address is 0x 4 00000000 for AST2700.
According to the design of QEMU, the dram container base address is 0x4 00000000(s->dram_mr).
Therefore, in the above example, the data should be moved to the dram container at address 0.
I created two variables to save the different base address.
A dma_dram_addr is used to save the real address.
A dram_addr is used to save the address for dram container(s->dram_as)
Example:
dma_dram_addr is 0x4 00000000
(uint64) s->regs[R_DMA_DRAM_ADDR_HIGH] << 32) |s->regs[R_DMA_DRAM_ADDR]
dram_addr is 0
dram_addr = 0x400000000(real address) - 0x400000000(dram container base address) to get the address for dram contained for moving
dram_addr = dma_dram_addr - s->dram_mr->container->addr;
Finally, the following APIs could work properly.
data = address_space_ldl_le(&s->dram_as, dram_addr,
MEMTXATTRS_UNSPECIFIED, &result);

This function return type is void.
If I understand your request, do you mean do the following changes?
static bool aspeed_soc_ast2700_gic(DeviceState *dev, Error **errp) --> change return type bool
{
---
gicbusdev = SYS_BUS_DEVICE(a->intc.gic);
if(!sysbus_realize(gicbusdev, errp)) {
return false;
}
---
return true;
}
Then,
/* GIC */
if(!aspeed_soc_ast2700_gic(dev, errp)) {
return;
}

OK. There are two problems to address, the "zero" length transfer and
the DMA length unit, which is missing today. Newer SoC use a 1 bit / byte
and older ones, AST2400 and AST2500, use 1 bit / 4 bytes.
We can introduce a AspeedSMCClass::dma_len_unit and rework the loop to :
do {
....
if (s->regs[R_DMA_LEN]) {
s->regs[R_DMA_LEN] -= 4 / asc->dma_len_unit;
}
} while (s->regs[R_DMA_LEN]);
It should fix the current implementation.
I don't think this is necessary to add a Fixes tag because the problem
has been there for ages and no one reported it. Probably because the
only place DMA transfers are used is in U-Boot and transfers have a
non-zero length.
> Currently, only supports dma length 4 bytes aligned.
this looks like a third topic. So the minimum value R_DMA_LEN should
have on the AST2600 SoC and above is '3'. I would opt to replace the
DMA_LENGTH macro with a dma_length_sanitize() helper to fix the software
input of R_DMA_LEN.
Thanks,

It seems that the R_DMA_LEN register is set by FW without taking
into account the length unit ( bit / 4 bytes). Would you know why ?
If I change the model to match 1 bit / 4 bytes unit of the R_DMA_LEN
register. Linux fails to boot. I didn't dig further and this is
something we need to understand before committing.

Is this 4 bytes alignment new for the AST2700 or is this something
you added because the mask of DMA_LENGTH is now relaxed to match
all addresses ?
#define DMA_LENGTH(val) ((val) & 0x01FFFFFF)

Could you please share the specs of the R_DMA_DRAM_ADDR and
R_DMA_DRAM_ADDR_HIGH registers to see what are the init values,
how these registers should be set, their alignment constraints
if any, how the values evolve while the HW does the DMA transactions,
etc.

This line make user input data length 4 bytes alignment.
https://github.com/AspeedTech-BMC/u-boot/blob/aspeed-master-v2019.04/arch/arm/mach-aspeed/ast2500/utils.S#L35
This line set the value of count parameter to AST_FMC_DNA_LENGTH.
AST_FMC_DMA_LENGTH is 4 bytes alignment value.
Example: input 4
((4+3)/4) * 4 --> (7/4) *4 ---> 4
If AST_FMC_DMA_LENGTH is 0, it means it should move 4 bytes data and AST_FMC_DMA_LENGTH do not need to be divided by 4.

AST2700, AST2600 and AST1030 is from 1 byte to 1FFFFFF, so I change this Micro to fix data lost.
https://github.com/AspeedTech-BMC/u-boot/blob/aspeed-master-v2023.10/arch/arm/mach-aspeed/ast2700/spi.c#L186
Please see this line, it decrease dma_len 1 byte first then, set to DMA_LEN register because DMA_LEN is 0 which means should move 1 byte data if DMA enables for AST2600, AST1030 and AST2700.

Only AST2500 need 4 bytes alignment for DMA Length. However, according to the design of sapped_smc_dma_rw function,
it utilizes address_space_stl_le API and it only works data 4 bytes alignment. https://github.com/qemu/qemu/blob/master/hw/ssi/aspeed_smc.c#L889
For example,
If users want to move 0x101 data_length, after 0x100 data has been moved and remains 1 byte data need to be moved.
Please see this line program, https://github.com/qemu/qemu/blob/master/hw/ssi/aspeed_smc.c#L940
```
s->regs[R_DMA_LEN] -= 4;
```
The value of s->regs[R_DMA_LEN] becomes 0xffffffffXX because it is uint32_t data type and this while loop run in the unexpected behavior, https://github.com/qemu/qemu/blob/master/hw/ssi/aspeed_smc.c#L864
That was, why I set 4bytes alignment for all models.

Thanks for the info. It seems that there are no alignment constraints.
I am surprised that there are no limits for the length in the specs.
It's 32MB right ?
Previous SoCs hardwire the high bits of the address where DRAM is mapped
in the DMA DRAM address reg. This is why the DRAM container was introduced,
so that HW units doing DMAs, like SMC, didn't have to manipulate real
physical addresses and offsets could be used instead. AST2700 HW interface
is different.
We can't use 's->dram_mr->container->addr' directly and I would like to
avoid passing 'sc->memmap[ASPEED_DEV_SDRAM]' as a property to the model.
Also, I was hoping that we didn't have to update the high part of the
address in the 0x07c reg. It seems we have to.

So, U-Boot simply hardcodes the DRAM high bits
if (dma_dest >= ASPEED_DRAM_BASE)
writel(0x4, (void *)DRAM_HI_ADDR);
The fallback plan would simply be to ignore the high bits of the DMA
DRAM address. It should work today. Let me think about it more.
Thanks,
C.

yes. I don't see any 1bit / 4bytes conversion when setting the DMA_LEN
register. Am I mistaking ? That's not what the specs says.

ok. For that, I think you could replace aspeed_smc_dma_len() with
return QEMU_ALIGN_UP(s->regs[R_DMA_LEN] + asc->dma_start_length, 4);

Peter,
Could you please look at aspeed_soc_ast2700_gic() when you have some time ?
My GIC knowledge is a bit limited and I would feel more confortable with
your feedback.
The rest looks good to me.
Thanks,
C.

I don't think the gicint prefix is useful in the names. I am struggling to
catch what new_gicint_status and trigger really do.

Hello Jamin,
To handle the DMA DRAM Side Address High register, we should reintroduce
an "dram-base" property which I removed a while ago. Something like :

please call this variable dma_dram_offset, I found it less confusing.

With the new "dram-base" property, the above if can be replaced by :
dma_dram_offset = dma_dram_addr - s->dram_base;

After I discussed with designers, my explanation as below.
AST2500 datasheet description:
FMC8C: DMA Length Register
31:25 Reserved(0)
24:2 RW DMA_LENGTH
From 4bytes to 32MB
0: 4bytes
0x7FFFFF: 32MB
1:0 Reserved
If users set this register 0, SPI DMA controller would move 4 bytes data.
If users set this register bits[24:2] 0x7FFFFF, SPI DMC controller would move 32MB data because this register includes reserved bits [1:0].
Ex: bits 24:2 --> 0x7fffff
bits 1:0 --> 0 Reserved
bits[24:0] is (0x1FFFFFC + start length 4) --> 2000000 --> 32MB
111 1111 1111 1111 1111 1111 00
LENGTH[24:2] 7 F F F F F Reserved [1:0]
That was why AST2500 DMA length should 4 bytes alignment and you do not see handling length units because it includes reserved bits 1 and 0.
If user want to move 3 bytes data, our firmware set this register 4 ensure it 4bytes alignment and the value of register as following
bits[2:0] = "b100" Finally, SPI DMA controller move 8 bytes data(4bytes input count + start length 4bytes)
And that was why it set DMA_LENGTH 0x01FFFFFC
https://github.com/qemu/qemu/blob/master/hw/ssi/aspeed_smc.c#L187
#define DMA_LENGTH(val) ((val) & 0x01FFFFFC)
I want to change it to 0x01FFFFFF to support all ASPEED SOCs because AST2600, AST2700 and AST1030 use this register bit 0 and 1 whose unit is 1byte rather than 4 bytes.

This register is used to set the dram address. AST2700 support the maximum dram size is 8GiB.
If dram base address is 0x400000000, the address range of 8GiB size would be 0x400000000 - 0x600000000
32bits only support dram size 4GiB. That was why we need this High Part register to support 8GIB size.
Yes, the maximum moving data length for flash is 32MB and is set by SPI8C DMA LENGTH Register.

After I checked with our SPI deriver designers, we confirmed it was a bug.
Example: If users use 8GIB dram size, the address range of 8GiB size would be 0x400000000 - 0x600000000
cp.b 100220000 503000000 101 --> This command would move the date at dram address 403000000 rather than 503000000
Our u-boot firmware will fix it. Thanks for report it.
