As part of merging the next branch in to master, the sifive_fu540 will
fail to link:
riscv64-linux-ld.bfd: lib/built-in.o: in function `panic_finish':
lib/panic.c:28: undefined reference to `do_reset'
make[2]: *** [spl/u-boot-spl] Error 1
make[1]: *** [spl/u-boot-spl] Error 2
make: *** [sub-make] Error 2
And while the "fix the build" option of enabling CONFIG_SPL_SYSRESET may
solve the issue, it is unclear that it is the correct path exactly. For
the moment, I am reverting this commit and take a "revert the revert"
and proper fix as soon as it's available.
This reverts commit cdae446461191714d692190da1ad4344398adc57.

Add a support for SPL which will boot from L2 LIM (0x0800_0000) and
then SPL will boot U-Boot FIT image (OpenSBI FW_DYNAMIC + u-boot.bin)
from MMC boot devices.
SPL related code is leveraged from FSBL

When building U-Boot we select the architecture via Kconfig and not ARCH
being passed in via the environment or make cmdline.
While in here, add the doc file to the MAINTAINERS entry.

Move this uncommon header out of the common header.
Signed-off-by: Simon Glass <[email protected]>

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.

This patch adds SiFive FU540 board support. For now, only
SiFive serial, SiFive PRCI, and Cadance MACB drivers are
only enabled. The SiFive FU540 defconfig by default builds
U-Boot for S-Mode because U-Boot on SiFive FU540 will run
in S-Mode as payload of BBL or OpenSBI.
