2025-06-13m68k: drop pointless #if 0 blockRasmus Villemoes
The way DECLARE_GLOBAL_DATA_PTR is used, the stuff under #if 0 can never compile as you cannot have a non-constant initializer at global scope (and one would get linker errors as well because the 'gd' symbol would be defined in multiple TUs).

2024-10-23m68k: asm/ptrace.h: include linux/types.hRasmus Villemoes
Modifying a generic header like watchdog.h, removing not directly used asm/ptrace.h header relies on whoever includes it to already have included something that defines the type ulong. Make the asm/ptrace.h header self-contained by including the proper header.

2024-05-06global: Make <asm/global_data.h> include <asm/u-boot.h>Tom Rini
This follows the example of RISC-V where <asm/global_data.h> includes <asm/u-boot.h> directly as "gd" includes a reference to bd_info already and so the first must include the second anyhow. We then remove <asm/u-boot.h> from all of the places which include references to "gd" an so have <asm/global_data.h> already. Signed-off-by: Tom Rini <trini@konsulko.com>

2023-05-31m68k: use asm-generic/unaligned.hJens Wiklander
M68k essentially duplicates the content of asm-generic/unaligned.h, with an exception for non-Coldfire configurations. Coldfire configurations are apparently able to do unaligned accesses. But in an attempt to clean up and handle unaligned accesses in the same way we ignore that and use the common asm-generic/unaligned.h directly instead.

This driver is actually used for powerpc and m68k/ColdFire. On ColdFire SoC's, interrupt flag get not set if IIEN flag (mbcr bit6, interrupt enabled) is not set appropriately before each transfert.

The FSL eSDHC controller supports two reference clocks. They are platform clock and periperhal clock. The global variable sdhc_clk has already been used for platform clock.

2023-01-20global: Finish CONFIG -> CFG migrationTom Rini
At this point, the remaining places where we have a symbol that is defined as CONFIG_... are in fairly odd locations. While as much dead code has been removed as possible, some of these locations are simply less obvious at first. In other cases, this code is used, but was defined in such a way as to have been missed by earlier checks. Perform a rename of all such remaining symbols to be CFG_... rather than CONFIG_...

2021-06-23global_data: Ensure we have <config.h> when symbols are not in Kconfig yetTom Rini
All symbols that are defined in Kconfig will always be defined (or not) prior to preprocessing due to the -include directive while building. However, symbols which are not yet migrated will only be defined (or not) once the board config.h is included, via <config.h>. While the end goal must be to migrate all symbols, today we have cases where the size of gd will get mismatched within the build, based on include order. Mitigate this by making sure that any <asm/global_data.h> that uses symbols not in Kconfig does start with <config.h>. Remove this when not needed.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
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 <trini@konsulko.com>
