[PATCH v7 00/23] Fixes for Rockchip NFC driver part 1

[Johan Jonker]

This serie contains fixes for the Rockchip NFC driver,
which was ported to U-boot and merged with little review
and testing it seems.
Part 1 aims at passing the probe function without errors.
Extended with tree wide function cleanup needed for 64bit DT parsing.

Fixed are:
  64bit FDT parsing
  compatible string removal
  add missing layout structure
  add missing flash_node pointer
  add missing chip ID

Changed V7:
  add proof of concept for syscon node with variable reg size handling
  use another map_sysmem() function as cast
  remove cast

Changed V6:
  use -EINVAL on return
  drop cast
  use map_sysmem() function as cast
  add and rename patch

Changed V5:
  sort patch order
  add more fixes with pointer functions
  add debug text fixes
  test with binman for ARM only due to limited resources

Changed V4:
  fix cast and divider in syscon-uclass.c

Changed V3:
  use dev_read_addr_ptr
  fix oobfree

[PATCH v7 01/23] mtd: nand: raw: rockchip_nfc: use dev_read_addr_ptr

[Johan Jonker]

The fdt_addr_t and phys_addr_t size have been decoupled.
A 32bit CPU can expext 64-bit data from the device tree parser,
so use dev_read_addr_ptr in the rockchip_nfc.c file.

[PATCH v7 02/23] mtd: nand: raw: rockchip_nfc: remove the compatible string "rockchip,rk3308-nfc"

[Johan Jonker]

The compatible string for rk3308 has as fallback string
"rockchip,rv1108-nfc". As there is no logic in probe priority between
the SoC orientated string and the fall back, so remove the compatible
string "rockchip,rk3308-nfc" from the driver.

[PATCH v7 03/23] mtd: nand: raw: rockchip_nfc: add layout structure

[Johan Jonker]

The MTD framework in U-boot is not identical for drivers ported
from Linux. The rockchip_nfc driver was ported with OOB ops functions
while the framework expects a layout structure per chip.
Fix by adding a structure with OOB data and remove unused functions.

[PATCH v7 05/23] mtd: nand: raw: rockchip_nfc: fix oobfree offset and description

[Johan Jonker]

The MTD framework reserves 1 or 2 bytes for the bad block marker
depending on the bus size. The rockchip_nfc driver currently only
supports a 8 bit bus, but reserves standard 2 bytes for the BBM.
The first free OOB byte is therefore OOB2 at offset 2.
Page address(PA) bytes are moved to the last 4 positions before
ECC. Update the description for U-boot.

[PATCH v7 11/23] core: remap: fix regmap_init_mem_plat() reg size handeling

[Johan Jonker]

The fdt_addr_t and phys_addr_t size have been decoupled.
A 32bit CPU can expect 64-bit data from the device tree parser,
so convert regmap_init_mem_plat() input to handel both. The
syscon class driver also makes use of the regmap_init_mem_plat()
function, but has no way of knowing the format of the
device-specific platform data. In case of odd reg structures other
then that the syscon class driver assumes the regmap must be
filled in the individual syscon driver before pre-probe.
Also fix the ARRAY_SIZE divider in the syscon class driver.

[PATCH v7 12/23] rockchip: rk3288: syscon_rk3288: store syscon platdata in regmap

[Johan Jonker]

The Rockchip SoC rk3288 has 2 types of device trees floating around.
A 64bit reg size when synced from Linux and a 32bit for U-boot.
A pre-probe function in the syscon class driver assumes only 32bit.
For other odd reg structures the regmap must be defined in the individual
syscon driver. Store rk3288 platdata in a regmap before pre-probe
during bind.

Note:
  Proof of concept not tested with rk3288 hardware,
  but with rk3066.

[PATCH v7 18/23] drivers: use devfdt_get_addr_size_index_ptr when cast to pointer

[Johan Jonker]

The fdt_addr_t and phys_addr_t size have been decoupled. A 32bit CPU
can expect 64-bit data from the device tree parser, so use
devfdt_get_addr_size_index_ptr instead of the devfdt_get_addr_size_index
function in the various files in the drivers directory that cast to
a pointer.

[PATCH v7 20/23] drivers: use devfdt_get_addr_ptr when cast to pointer

[Johan Jonker]

The fdt_addr_t and phys_addr_t size have been decoupled. A 32bit CPU
can expect 64-bit data from the device tree parser, so use
devfdt_get_addr_ptr instead of the devfdt_get_addr function in
the various files in the drivers directory that cast to a pointer.

[PATCH v7 23/23] include: fdtdec: decouple fdt_addr_t and phys_addr_t size

[Johan Jonker]

The DT specification supports CPUs with both 32-bit and 64-bit addressing
capabilities. In U-boot the fdt_addr_t and phys_addr_t size are coupled
by a typedef. The MTD NAND drivers for 32-bit CPU's can describe partitions
with a 64-bit reg property. These partitions synced from Linux end up with
the wrong offset and sizes when only the lower 32-bit is passed.
Decouple the fdt_addr_t and phys_addr_t size as they don't necessary
match.

Sorry if you already responded and I missed it.

I don't understand this line. It looks like sizeof(fdt_addr_t) is
still 4 on 32-bit machines. So what does this actually mean?

The original response on WHY we need it for partitions:
https://lore.kernel.org/u-boot/7256f237-4b7b-f7d7-834f-f7c3fb8984d7@gmail.com/T/#m81afcb203e2309c05ca97d36c63ef758cf3cef89

Below an explanation of the consequences.
Does this text below help?

Current (coupled):
   phys_addr_t       fdt_addr_t
1: 32bit             32bit (problem: not enough bits to describe NAND partitions)
2: 64bit             64bit

New (decoupled)
   phys_addr_t       fdt_addr_t
1: 32bit             32bit (problem: not enough bits to describe NAND partitions)
2: 64bit             64bit
3: 32bit             64bit (Current U-boot DT with rk3288 32bit reg size DT)
4: 32bit             64bit (Synced rk3288 Linux 64bit reg size DT)

===

For situation 3 and 4:

In sandbox a 64bit addr is cast back to phys_addr_t and then to pointer of a memory area.
On real hardware a 64bit addr is cast to uintptr_t and then to a pointer.

In this serie we fix the functions that have a wrong cast on the same line and are easy to find:
-	data->base = (void *)dev_read_addr(dev);
+	data->base = dev_read_addr_ptr(dev);

This makes it pass the test.

Not fixed are drivers that cast later on:

	addr_base = dev_read_addr(dev);
	if (addr_base == FDT_ADDR_T_NONE)
		return -EINVAL;

	priv->regs = (void __iomem *)addr_base;

These drivers must be fixed by there MAINTAINERS if they like to enable decoupling.
This passes the test as long as they don't use it.

===

From io.h:

/* For sandbox, we want addresses to point into our RAM buffer */
static inline void *map_sysmem(phys_addr_t paddr, unsigned long len)
{
	return map_physmem(paddr, len, MAP_WRBACK);
}

===

From compiler.h:
/* Type for `void *' pointers. */
typedef unsigned long int uintptr_t;

From mapmem.h

/* Define a null map_sysmem() if the architecture doesn't use it */
# ifdef CONFIG_ARCH_MAP_SYSMEM
#include <asm/io.h>
# else
static inline void *map_sysmem(phys_addr_t paddr, unsigned long len)
{
	return (void *)(uintptr_t)paddr;
}

===

U-boot 32bit size:

	noc: syscon@ffac0000 {
		compatible = "rockchip,rk3288-noc", "syscon";
		reg = <0xffac0000 0x2000>;
		u-boot,dm-pre-reloc;
	};

struct dtd_rockchip_rk3288_noc {
	fdt32_t		reg[2];
};
static struct dtd_rockchip_rk3288_noc dtv_syscon_at_ffac0000 = {
	.reg			= {0xffac0000, 0x2000},
};

===

Linux 64bit reg size:

	noc: syscon@ffac0000 {
		compatible = "rockchip,rk3288-noc", "syscon";
		reg = <0x0 0xffac0000 0x0 0x2000>;
		u-boot,dm-pre-reloc;
	};

struct dtd_rockchip_rk3288_noc {
	fdt64_t		reg[2];
};
static struct dtd_rockchip_rk3288_noc dtv_syscon_at_ffac0000 = {
	.reg			= {0xffac0000, 0x2000},
};

Yes, I think I was reading it more generally, but here you are just
talking about partitions.
