[U-Boot] [PATCH 1/2] armv8: calculate __bss_size in u-boot-spl.lds

[Oded Gabbay <oded.gabbay@gmail.com>]

This patch adds a missing __bss_size symbol to the default armv8
u-boot-spl.lds file.
Makefile.spl relies on __bss_size to be present when it creates the SPL
image. It uses that symbol to create a pad file that will be used to place
the dtb after the bss section.
In ARMv8 default u-boot-spl.lds, __bss_size was missing and therefore, the
pad file was always 0. As a result, the dtb was placed after
_image_binary_end, which caused a failure when loading it inside the SPL.
