arm: ti: Introduce back omap4 support

2026-06-17T15:50:36Z

omap4 support was dropped by b0ee3fe642c ("arm: ti: Remove omap4 platform support") because the supported boards hadn't done the conversion to CONFIG_DM_I2C in time. It still exists some omap4-based products and they could benefit from the latest U-Boot support for obvious security reasons. Revert part of b0ee3fe642c to introduce back a minimal support for the omap4 platform. Fix the checkpatch's warning/errors induced by this revert. Following warnings are still present: | arch/arm/include/asm/arch-omap4/clock.h:445: WARNING: added, moved or deleted file(s), does MAINTAINERS need updating? | arch/arm/mach-omap2/omap4/hwinit.c:24: WARNING: Use 'if (IS_ENABLED(CONFIG...))' instead of '#if or #ifdef' where possible | arch/arm/mach-omap2/omap4/sdram_elpida.c:142: CHECK: Avoid CamelCase: | arch/arm/mach-omap2/omap4/sdram_elpida.c:143: CHECK: Avoid CamelCase: | arch/arm/mach-omap2/omap4/sdram_elpida.c:144: CHECK: Avoid CamelCase: | arch/arm/mach-omap2/omap4/sdram_elpida.c:145: CHECK: Avoid CamelCase: | arch/arm/mach-omap2/omap4/sdram_elpida.c:146: CHECK: Avoid CamelCase: | arch/arm/mach-omap2/omap4/sdram_elpida.c:147: CHECK: Avoid CamelCase: | arch/arm/mach-omap2/omap4/sdram_elpida.c:148: CHECK: Avoid CamelCase: | arch/arm/mach-omap2/omap4/sdram_elpida.c:149: CHECK: Avoid CamelCase: | arch/arm/mach-omap2/omap4/sdram_elpida.c:150: CHECK: Avoid CamelCase: | arch/arm/mach-omap2/omap4/sdram_elpida.c:151: CHECK: Avoid CamelCase: | arch/arm/mach-omap2/omap4/sdram_elpida.c:152: CHECK: Avoid CamelCase: | arch/arm/mach-omap2/omap4/sdram_elpida.c:153: CHECK: Avoid CamelCase: | arch/arm/mach-omap2/omap4/sdram_elpida.c:154: CHECK: Avoid CamelCase: | arch/arm/mach-omap2/omap4/sdram_elpida.c:155: CHECK: Avoid CamelCase: | arch/arm/mach-omap2/omap4/sdram_elpida.c:156: CHECK: Avoid CamelCase: | arch/arm/mach-omap2/omap4/sdram_elpida.c:157: CHECK: Avoid CamelCase: | arch/arm/mach-omap2/omap4/sdram_elpida.c:158: CHECK: Avoid CamelCase: | arch/arm/mach-omap2/omap4/sdram_elpida.c:159: CHECK: Avoid CamelCase: | arch/arm/mach-omap2/omap4/sdram_elpida.c:209: CHECK: Avoid CamelCase: | arch/arm/mach-omap2/omap4/sdram_elpida.c:210: CHECK: Avoid CamelCase: | arch/arm/mach-omap2/omap4/sdram_elpida.c:213: CHECK: Avoid CamelCase: | arch/arm/mach-omap2/omap4/sdram_elpida.c:215: CHECK: Avoid CamelCase: | arch/arm/mach-omap2/omap4/sdram_elpida.c:216: CHECK: Avoid CamelCase: | arch/arm/mach-omap2/omap4/sdram_elpida.c:217: CHECK: Avoid CamelCase: I didn't find an clean way to fix the "don't use #ifdef" warning as we need to define the gpio_bank for the SPL build only. For the CamelCase warnings, the incriminated attributes represent timings, so IMHO, it is more readable with CamelCase. Set myself as OMAP4 maintainer. Signed-off-by: Bastien Curutchet

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12Z

When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini

ARM: omap4: add platform specific info for GPMC and ELM controllers

2014-05-23T20:12:02Z

This patch moves platform specific information for GPMC and ELM controller into separate header files, so that any derivative devices do not mess other header files. Platform specific information added into arch-xx/../hardware.h - CPU related platform specific details like base-address of GPMC and ELM Platform specific information added into arch-xx/../mem.h - Generic configs for GPMC and ELM initialization. - Hardware parameters or constrains specific to GPMC and ELM IP like; number of max number of chip-selects available Signed-off-by: Pekon Gupta

mtd: nand: omap: merge duplicate GPMC data from different arch-xx headers into common omap_gpmc.h

2014-03-04T23:23:54Z

Each SoC platform (AM33xx, OMAP3, OMAP4, OMAP5) has its own copy of GPMC related defines and declarations scattered in SoC platform specific header files like include/asm/arch-xx/cpu.h However, GPMC hardware remains same across all platforms thus this patch merges GPMC data scattered across different arch-xx specific header files into single header file include/asm/arch/omap_gpmc.h Build tested using: ./MAKEALL -s am33xx -s omap3 -s omap4 -s omap5 Signed-off-by: Pekon Gupta
