[U-Boot] [PATCH 1/2] configs: Replace CONFIG_ISW_ENTRY_ADDR with CONFIG_SYS_TEXT_BASE

[Faiz Abbas]

Since 7e0ed13 ("Convert ARCH_OMAP2PLUS boards' CONFIG_SYS_TEXT_BASE to
Kconfig"), a default SYS_TEXT_BASE was set for all ARCH_OMAP2PLUS devices.
CONFIG_ISW_ENTRY_ADDR is used to set SYS_TEXT_BASE in qspi boot.

Simplify this by directly assigning SYS_TEXT_BASE in the defconfig.

[U-Boot] [PATCH 2/2] ARM: AM43XX: Call hw_data_init() again after relocation to update *ctrl

[Faiz Abbas]

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.
