   8 Compiling SPL is always tricky as it needs to fit limited resources.
   9 Fortunately in most cases there is no need to replace SPL or TPL while
  10 flashing a new firmware.
  11
  12 Compiling SPL for BCM4908 seems to fail with non-Broadcom toolchain:
  13 aarch64-openwrt-linux-musl-ld.bfd: u-boot-spl section `.u_boot_list' will not fit in region `.sram'
  14 aarch64-openwrt-linux-musl-ld.bfd: section .bss VMA [00000000822b9000,00000000822b93ef] overlaps section .u_boot_list VMA [00000000822b8f60,00000000822b9a87]
  15 aarch64-openwrt-linux-musl-ld.bfd: region `.sram' overflowed by 2696 bytes
  16
  17 It also requires hashtable.h which has to be generated using some
  18 Broadcom's custom perl script that isn't integrated as this point.
  19
  20 For now just disable SPL and use only last-stage U-Boot that must be
  21 shipped with every firmware.
