[PATCH v2 00/11] Add Chameleon v3 support

[PATCH v2 00/11] Add Chameleon v3 support

[Paweł Anikiel]

The Google Chameleon v3 is a board made for testing both video and audio
interfaces of external devices. It has a connector compatible with the
Mercury+ AA1 module, which itself contains an Arria 10 SoCFPGA. The AA1
module comes in a few different configurations, the Chameleon V3 supports
ME-AA1-270-3E4-D11 and ME-AA1-480-2I3-D12E.

This patchset adds support for the Chameleon v3 (both versions), as well
as some bugfixes and optimizations, mostly in Arria 10 code.

V2:
  Adjust devicetrees so that they work both in u-boot and linux
  Put u-boot-specific parts of devicetrees into *-u-boot.dtsi files
  Minor changes in Kconfig, defconfig, and config.h

Paweł Anikiel (11):
  arm: dts: Add Mercury+ AA1 devicetrees
  arm: dts: Add Chameleonv3 handoff headers
  arm: dts: Add Chameleonv3 devicetrees
  board: Add Chameleonv3 board dir
  config: Add Chameleonv3 config
  misc: atsha204a: Increase wake delay by tWHI
  sysreset: socfpga: Use parent device for reading base address
  socfpga: arria10: Replace delays with busy waiting in cm_full_cfg
  socfpga: arria10: Improve bitstream loading speed
  socfpga: arria10: Wait for fifo empty after writing bitstream
  socfpga: arria10: Allow dcache_enable before relocation

[PATCH v2 06/11] misc: atsha204a: Increase wake delay by tWHI

[Paweł Anikiel]

From the ATSHA204A datasheet (document DS40002025A):

Wake: If SDA is held low for a period greater than tWLO, the device
exits low-power mode and, after a delay of tWHI, is ready to receive
I2C commands.

tWHI value can be found in table 7-2.

[PATCH v2 07/11] sysreset: socfpga: Use parent device for reading base address

[Paweł Anikiel]

This driver is a child of the rstmgr driver, both of which share the
same devicetree node. As a result, passing the child's udevice pointer
to dev_read_addr_ptr results in a failure of reading the #address-cells
property. Use the parent udevice pointer instead.

[PATCH v2 08/11] socfpga: arria10: Replace delays with busy waiting in cm_full_cfg

[Paweł Anikiel]

Using udelay while the clocks aren't fully configured causes the timer
system to save the wrong clock rate. Use sdelay and wait_on_value
instead (the values used in these functions were found experimentally).

[PATCH v2 09/11] socfpga: arria10: Improve bitstream loading speed

[Paweł Anikiel]

Apply some optimizations to speed up bitstream loading
(both for full and split periph/core bitstreams):

 * Change the size of the first fs read, so that all the subsequent
   reads are aligned to a specific value (called MAX_FIRST_LOAD_SIZE).
   This value was chosen so that in subsequent reads the fat fs driver
   doesn't have to allocate a temporary buffer in get_contents
   (assuming 8KiB clusters).

 * Change the buffer size to a larger value when reading to ddr
   (but not too large, because large transfers cause a stack overflow
   in the dwmmc driver).

[PATCH v2 10/11] socfpga: arria10: Wait for fifo empty after writing bitstream

[Paweł Anikiel]

For some reason, on the Mercury+ AA1 module, calling
fpgamgr_wait_early_user_mode immediately after writing the peripheral
bitstream leaves the fpga in a broken state (ddr calibration hangs).
Adding a delay before the first sync word is written seems to fix this.
Inspecting the fpgamgr registers before and after the delay,
imgcfg_FifoEmpty is the only bit that changes. Waiting for this bit
(instead of a hardcoded delay) also fixes the issue.

[PATCH v2 11/11] socfpga: arria10: Allow dcache_enable before relocation

[Paweł Anikiel]

Before relocating to SDRAM, the ECC is initialized by clearing the
whole SDRAM. In order to speed this up, dcache_enable is used (see
sdram_init_ecc_bits).

Since commit 503eea451903 ("arm: cp15: update DACR value to activate
access control"), this no longer works, because running code in OCRAM
with the XN bit set causes a page fault. Override dram_bank_mmu_setup
to disable XN in the OCRAM and setup DRAM dcache before relocation.

In dwmci_send_cmd (at drivers/mmc/dw_mmc.c:243). It stack-allocates a
buffer of size sizeof(struct dwmci_idmac) * (data->blocks / 8). Since
loading the bitstream is done from SPL (which is still in sram), we
only have about 100K of stack, which is not enough to load an 11MB
file in one go.

All looks fine to me, I'm in the progress to consolidate all socfpga patches for PR this Friday.

This change breaking the socfpga_stratix10_atf_defconfig build(all aarch64 socfpga are impacted), can you fix it ?
