Subject: ARM: AM43XX: Call hw_data_init() again after relocation to update *ctrl
X-Git-Url: http://git.dujemihanovic.xyz/login.html?a=commitdiff_plain;h=a93feb2edc60b9db76ec794bff5ad0fcb10ce3eb;p=u-boot.git

ARM: AM43XX: Call hw_data_init() again after relocation to update *ctrl

hw_data_init() is called before relocation to initialise hardware data.
Since ctrl is initialized to OMAP_SRAM_SCRATCH_SYS_CTRL in
arch/arm/mach-omap2/am33xx/hw_data.c, the pointer *ctrl will not be
updated during relocation and will hold a stale value.

Therefore call hw_data_init() again after relocation to
reinitialize *ctrl.
