It would be nice to collect them into include/linux/delay.h like Linux. While we are here, fix the ndelay() implementation; I used the DIV_ROUND_UP() instead of (x)/1000 because it must wait *longer* than the given period of time.

* Use separate options for TPL supportSimon Glass2016-09-16-6/+9
| | | | | | | | | | | | | | | At present TPL uses the same options as SPL support. In a few cases the board config enables or disables the SPL options depending on whether CONFIG_TPL_BUILD is defined. With the move to Kconfig, options are determined for the whole build and (without a hack like an #undef in a header file) cannot be controlled in this way. Create new TPL options for these and update users. This will allow Kconfig conversion to proceed for these boards. Signed-off-by: Simon Glass <sjg@chromium.org>

This commit is cherry-picking useful macros from include/linux/bug.h of Linux 4.4. I did not import BUILD_BUG_ON_MSG() because it would not work if it is used with include/common.h in U-Boot.

| | | | | | | | | | | | | | | This patch adds support for LZ4-compressed FIT image contents. This algorithm has a slightly worse compression ration than LZO while being nearly twice as fast to decompress. When loading images from a fast storage medium this usually results in a boot time win. Sandbox-tested only since I don't have a U-Boot development system set up right now. The code was imported unchanged from coreboot where it's proven to work, though.

We have been trying to trim down common.h and put separate functions into separate header files and that change goes in the opposite direction. Move malloc_cache_aligned() to a new header so that this can be avoided. The header would perhaps be better named as alignmem.h but it needs to be included after common.h and people might be confused by this.

* efi: Add support for loading U-Boot through an EFI stubSimon Glass2015-08-05-0/+7
| | | | | | | | | | | | | | | | | | | | It is useful to be able to load U-Boot onto a board even if is it already running EFI. This can allow access to the U-Boot command interface, flexible booting options and easier development. The easiest way to do this is to build U-Boot as a binary blob and have an EFI stub copy it into RAM. Add support for this feature, targeting 32-bit initially. Also add a way to detect when U-Boot has been loaded via a stub. This goes in common.h since it needs to be widely available so that we avoid redoing initialisation that should be skipped.

* powerpc/mpc85xx: Remove some dead codeScott Wood2015-04-20-1/+0
| | | | | | | | | | | | | | | | | | | U-Boot does not have system calls (the services it exposes to standalone commands use a different mechanism), so the syscall handler is dead code. It's also broken code, as it assumes it is located at 0xc00 -- while even before the patch to stop relocating exception vectors to 0, U-Boot had the syscall at 0x900. The critical and machine check return paths are never called -- the regular exception return path is used instead, which works because xSRR0/1 have already been saved and can be restored via the regular SRR0/1 (we don't care too much in U-Boot about taking a critical/mcheck inside another exception prolog/epilog).
