We have a pin from AP to EC, called AP_IN_SLEEP_L (SRCLKENA0 on AP side,

The romstage main() entry point on arm64 boards is usually in mainboard
code, but there are a handful of lines that are always needed in there
and not really mainboard specific (or chipset specific). We keep arguing
every once in a while that this isn't ideal, so rather than arguing any
longer let's just fix it. This patch moves the main() function into arch
code with callbacks that the platform can hook into. (This approach can
probably be expanded onto other architectures, so when that happens this
file should move into src/lib.)
Tested on Cheza and Kevin. I think the approach is straight-forward
enough that we can take this without testing every board. (Note that in
a few cases, this delays some platform-specific calls until after
console_init() and exception_init()... since these functions don't
really take that long, especially if there is no serial console
configured, I don't expect this to cause any issues.)

MT8183 only allows booting from eMMC, so we have to do eMMC emulation
from an external source, for example EC, which makes the size of
bootblock very important.
A fully functional bootblock (that can boot into verstage or romstage)
is about 38000 bytes. If self decompression (CONFIG_COMPRESS_BOOTBLOCK)
is enabled, only 25088 (66%) bytes are needed.
