X-Git-Url: http://git.dujemihanovic.xyz/login.html?a=commitdiff_plain;h=f2c644e0b8bc7dc842c8b27e65c69e503687296f;p=u-boot.git

tools: kwboot: Patch destination address to DDR area for SPI image

SPI/NOR kwbimage may have destination address set to 0xFFFFFFFF, which
means that the image is not downloaded to DDR but rather it is executed
directly from SPI/NOR. In this case execution address is set to SPI/NOR
area.

When patching image to UART type, change destination and execution
addresses from SPI/NOR XIP area to DDR area 0x00800000 (which is default
for A38x).
