arm: Remove cm_t335 board

2022-08-21T01:18:15Z

This board is behind on several mandatory DM migrations and is missing OF_CONTROL support that makes other conversions impossible. Remove it. Cc: Igor Grinberg Cc: Nikita Kiryanov Cc: Uri Mashiach Signed-off-by: Tom Rini

linker_lists: Rename sections to remove . prefix

2022-06-23T16:58:18Z

Rename the sections used to implement linker lists so they begin with '__u_boot_list' rather than '.u_boot_list'. The double underscore at the start is still distinct from the single underscore used by the symbol names. Having a '.' in the section names conflicts with clang's ASAN instrumentation which tries to add redzones between the linker list elements, causing expected accesses to fail. However, clang doesn't try to add redzones to user sections, which are names with all alphanumeric and underscore characters. Signed-off-by: Andrew Scull Reviewed-by: Simon Glass

imx: imx8mm-cl-iot-gate: enable pinctrl_wdog in SPL

2022-06-14T19:33:14Z

Mark pinctrl_wdog as u-boot,dm-spl to clean up board code, The set_wdog_reset() function is not necessary as this is handled by the imx_watchdog.c driver due to the 'fsl,ext-reset-output' property being set. Signed-off-by: Peng Fan

imx: imx8mm-cl-iot-gate: Enable DM_SERIAL

Enable CONFIG_DM_SERIAL. uart3 and its pinmux was already marked with u-boot,dm-spl. Move preloader_console_init after spl_early_init to make sure driver model work. Signed-off-by: Peng Fan Reviewed-by: Fabio Estevam

imx8m: fix reading of DDR4 MR registers

2022-05-20T07:30:28Z

I was trying to employ lpddr4_mr_read() to something similar to what the imx8mm-cl-iot-gate board is doing for auto-detecting the RAM type. However, the version in drivers/ddr/imx/imx8m/ddrphy_utils.c differs from the private one used by that board in how it extracts the byte value, and I was only getting zeroes. Adding a bit of debug printf'ing gives me tmp = 0x00ffff00 tmp = 0x00070700 tmp = 0x00000000 tmp = 0x00101000 and indeed I was expecting a (combined) value of 0xff070010 (0xff being Manufacturer ID for Micron). I can't find any documentation that says how the values are supposed to be read, but clearly the iot-gate definition is the right one, both for its use case as well as my imx8mp-based board. So lift the private definition of lpddr4_mr_read() from the imx8mm-cl-iot-gate board code to ddrphy_utils.c, and add a declaration in the ddr.h header where e.g. get_trained_CDD() is already declared. This has only been compile-tested for the imx8mm-cl-iot-gate board (since I don't have the hardware), but since I've merely moved its definition of lpddr4_mr_read(), I'd be surprised if it changed anything for that board.

imx8mm-cl-iot-gate: Remove redundant board_fix_fdt()

2022-04-21T21:00:26Z

In arch/arm/mach-imx/imx8m/soc.c there's an implementation of board_fix_fdt() introduced by commit 35bb60787b88. Remove the redundant one to avoid failed to build from source when enabling CONFIG_OF_BOARD_FIXUP. Signed-off-by: Ying-Chun Liu (PaulLiu) Cc: Fabio Estevam Cc: uboot-imx Reviewed-by: Fabio Estevam

capsule: board: Add information needed for capsule updates

2022-04-15T08:43:18Z

Add a structure which defines the information that is needed for executing capsule updates on a platform. Some information in the structure like the dfu string is used for making the update process more robust while some information like the per platform image GUIDs is used for fixing issues. Initialise this structure in the board file, and use the information for the capsule updates. Signed-off-by: Sughosh Ganu

imx8mm-cl-iot-gate: Retrieve the DDR type from EEPROM

2022-04-12T17:10:44Z

Currently, the DDR type is retrieved by iteracting inside an array of possible DDR types. This may take saveral attempts, which slows the overall U-Boot process and does not provide a good user experience: U-Boot SPL 2021.07 (Feb 28 2022 - 06:39:32 +0000) DDRINFO: Cfg attempt: [ 1/6 ] DDRINFO(M): mr5-8 [ 0xff000010 ] DDRINFO(T): mr5-8 [ 0x5000010 ] resetting ...
