All of the spi flash drivers implement the status register polling for
detecting the device ready state, so unify them all in a new helper
function -- spi_flash_wait_ready.

PBL(pre-boot loader): SPI flash used as RCW(Reset Configuration Word) and
PBI(pre-boot initialization) source, CPC(CoreNet Platform Cache) used as
1M SRAM where PBL will copy whole U-BOOT image to, U-boot can boot from
CPC after PBL completes RCW and PBI phases.

And got wrong env data. So reset it in board early init.
We cannot use generic cfi flash routines, because flash_init() is

When bootstrapping ourselves on the fly at runtime (via "go"), we need to
turn off the caches to avoid taking software exceptions. Since caches
need CPLBs and CPLBs need exception handlers, but we're about to rewrite
the code in memory where those exception handlers live, we need to turn
off caches first.
This new code also encourages a slight code optimization by storing the
MMR bases in dedicated registers so we don't have to fully load up the
pointer regs multiple times.
