2021-09-23lmb: nios2: Add arch_lmb_reserve()Marek Vasut1-0/+16
Add arch_lmb_reserve() implemented using arch_lmb_reserve_generic(). It is rather likely this architecture also needs to cover U-Boot with LMB before booting Linux.

2021-02-02common: Drop asm/global_data.h from common headerSimon Glass3-0/+5
Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

2020-05-19command: Remove the cmd_tbl_t typedefSimon Glass3-3/+6
We should not use typedefs in U-Boot. They cannot be used as forward declarations which means that header files must include the full header to access them. Drop the typedef and rename the struct to remove the _s suffix which is now not useful. This requires quite a few header-file additions. Signed-off-by: Simon Glass <sjg@chromium.org>

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini30-68/+33
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>

Convert the nios2 architecture to make use of the new asm-generic/io.h to provide address mapping functions. As nios2 actually performs non-identity mapping between physical & virtual addresses we can't simply make use of the generic functions, with the exception of being able to drop our no-op unmap_physmem() and definitions of unused map flags.

2017-05-01fdt: Move fdt_fixup_ethernet to a common placeTom Rini2-39/+0
With 3f66149d9fb4 we no longer have a common call fdt_fixup_ethernet. This was fine to do on PowerPC as they largely had calls already in ft_cpu_fixup. On ARM however we largely relied on this call. Rather than introduce a large number of changes to ft_cpu_fixup / ft_board_fixup we recognize that this is a common enough call that we should be doing it in a central location. Do it early enough that we can do any further updates in ft_cpu_fixup / ft_board_fixup.
