ARM: arm11: Add C wrapper for allow_unaligned()

2023-07-01T15:29:15Z

Rename current assembler implementation of allow_unaligned() to arm11_arch_cp15_allow_unaligned() and add it into arm11.h header, then add C wrapper of allow_unaligned(). This fixes misbehavior when linking U-Boot, where the CPU specific allow_unaligned() implementation was ignored and instead the __weak allow_unaligned() implementation from lib/efi_loader/efi_setup.c was used, which led to "data abort" just before booting Linux via tftp, in efi_dp_from_file() -> path_to_uefi() -> utf16_put() . The problem is triggerd by c7c0ca37673 ("efi_loader: fix efi_dp_from_file()") . Adding the wrapper fixes the problem.

ARM: armv7: Add C wrapper for allow_unaligned()

2023-07-01T15:29:15Z

Rename current assembler implementation of allow_unaligned() to v7_arch_cp15_allow_unaligned() and add it into armv7.h header, then add C wrapper of allow_unaligned(). This fixes misbehavior when linking U-Boot on ARMv7a i.MX6Q, where the CPU specific allow_unaligned() implementation was ignored and instead the __weak allow_unaligned() implementation from lib/efi_loader/efi_setup.c was used, which led to "data abort" just before booting Linux via tftp, in efi_dp_from_file() -> path_to_uefi() -> utf16_put() .

ddr: imx93: update the ddr init to support mult setpoints

2023-05-21T14:54:41Z

Update the DDR init flow for multi-setpoint support on i.MX93. A new fsp_cfg struct need to be added in the timing file to store the diff part of the DDRC and DRAM MR register for each setpoint. Signed-off-by: Jacky Bai Reviewed-by: Ye Li Signed-off-by: Peng Fan

ddr: imx9: Add workaround for DDRPHY rank-to-rank errata

2023-05-21T14:54:41Z

According to DDRPHY errata, the Rank-to-Rank Spacing and tphy_rdcsgap specification does not include the Critical Delay Difference (CDD) to properly define the required rank-to-rank read command spacing after executing PHY training firmware. Following the errata workaround, at the end of data training, we get all CDD values through the MessageBlock, then re-configure the DDRC timing of WWT/WRT/RRT/RWT with comparing MAX CDD values.
