arm: imx: remove unnecessary volatile qualifiers from "save gd" variables

2025-06-13T22:57:15Z

Now that the global gd pointer is no longer volatile-qualified, there's no reason for the temporary variables used for saving/restoring it to have that qualifier. Signed-off-by: Rasmus Villemoes Tested-by: Anshul Dalal

imx: fix get_boot_device() for imx8

2023-05-02T08:57:32Z

commit 787f04bb6a0a ("imx: add USB2_BOOT type") broke get_boot_device() for IMX8 which affects booting from SDP due to boot_instance being non-zero. Fix this by only using boot_instance for imx8ulp and imx9. Fixes: 787f04bb6a0a ("imx: add USB2_BOOT type") Signed-off-by: Tim Harvey Reviewed-by: Peng Fan Reviewed-by: Fabio Estevam

ARM: imx: Reinstate decode ECSPI env location from i.MX8M ROMAPI tables

2023-01-30T22:23:01Z

Decode ECSPI boot device in env_get_location() from i.MX8M ROMAPI tables. This is necessary to correctly identify env is in SPI NOR when the system boots from SPI NOR attached to ECSPI. This reinstates change from commit: e26d0152d61 ("ARM: imx: Decode ECSPI env location from i.MX8M ROMAPI tables") which has been dropped in commit: b0a284a7c94 ("imx: move get_boot_device to common file") Fixes: b0a284a7c94 ("imx: move get_boot_device to common file") Signed-off-by: Marek Vasut Reviewed-by: Fabio Estevam

imx: move get_boot_device to common file

2022-07-26T09:29:00Z

i.MX8MN/P/ULP supports ROM API, they have almost same get_boot_device implementation, so move to a common file. And when support i.MX9, no need to include the other function copy. Since sys_proto.h is included in imx_romapi.c, there will be build warning for i.MX8M because wdog_regs not defined, so include imx-regs.h in i.MX8M sys_proro.h Signed-off-by: Peng Fan

imx8: add rom api wrappers

2022-07-25T13:35:34Z

The ROM API is thoroughly undocumented, but apparently passing the xor of the real arguments as an extra argument is required [1]. Also, we need to do the "save gd/restore gd" dance. These are both error-prone, and lead to a lot of code duplication. Since both imx8m[np] and imx8ulp SOCs have this, add a separate translation unit which is included precisely when the new CONFIG_IMX8_ROMAPI symbol is set, which provide convenience wrappers that take care of computing the xor value as well as doing the gd dance, and that thus have a more intuitive API. Subsequent patches will make use of these to reduce boilerplate. [1] One wonders, for example, if the check is only applied to the lower 32 bits, or if we're implicitly relying on all 64-bit pointer values we're passing effectively have 0 in the upper 32 bits.
