6.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Vijendar Mukunda <Vijendar.Mukunda@xxxxxxx>
[ Upstream commit c56ba3e44784527fd6efe5eb7a4fa6c9f6969a58 ]
The existing code modifies IRAM and DRAM size after sha dma start for
vangogh platform. The problem with this sequence is that it might cause
sha dma failure when firmware code binary size is greater than the default
IRAM size. To fix this issue, Move the iram-dram fence register sequence
prior to sha dma start.
