Subject: spi: sh_qspi: Drop SPBDCR wait
X-Git-Tag: v2018.05-rc2~18^2~4
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=118226495249268a35e604b2e6309801699f6224;p=u-boot

spi: sh_qspi: Drop SPBDCR wait

Waiting for SPBDCR == 1 is not required and is covered by the
subsequent wait for SPSR_SPRFF, so drop this.
