Subject: zynqmp: qspi: Move the trasmit buffer pointer
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=23681b62df71dfb3e4c9cf676366c9d074e42f93;p=thirdparty%2Fu-boot.git

zynqmp: qspi: Move the trasmit buffer pointer

Move the transmit buffer pointer by the size
we already sent. This fixes the issue of qspi
write if the length to be written is not
the exponent of 2.
