Subject: zynq: Use arch_cpu_init() instead of lowlevel_init()
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=262f08d6ea18a62f827b8ccb60f355ca2eaf6e2b;p=u-boot.git

zynq: Use arch_cpu_init() instead of lowlevel_init()

Zynq lowlevel_init() was implemented in C but stack
pointer is setup after function call in _main().
Move architecture setup to arch_cpu_init() which is call
as the first function in board_init_f() which
already have correct stack pointer.
