6 years agosandbox: Boot in U-Boot through the standard call

sandbox: Boot in U-Boot through the standard call

Most architectures use jump_to_image_no_args() to jump from SPL to U-Boot.
At present sandbox is special in that it jumps in its
spl_board_load_image() call. This is not strictly correct, and means that
sandbox misses out some parts of board_init_r(), just as calling
bloblist_finish(), for example.

single call, but if we call from TPL -> SPL -> U-Boot the arguments build

cros_ec: Use uint instead of u8 for parameters

There is no advantage to using a u8 for function parameters. It forces
the compiler to mask values and can increase code size. Also the command
enum has been extended to 16 bits. Update the functions to use uint
instead.

arm64: mvebu: a8k: autodetect RAM size

external DIMM. Hard coding the RAM size in the device-tree is not
convenient. Fortunately, the ATF that initializes the RAM knows the size
of RAM, and U-Boot can query the ATF using a SMC call.

The ATF maps the lower 3G of RAM starting at address 0. Higher RAM is
mapped at 4G. This leaves a 1G hole between 3G and 4G for IO
peripherals. Use a second bi_dram[] entry to describe the higher RAM
area. As a result, CONFIG_NR_DRAM_BANKS must be set to 2 to use more
than 3GB RAM.
