Subject: arm64: dts: ti: k3-am64-main: Update TF-A load address to workaround USB DFU limitation
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=3de27ef12ccb50205e602d92f29d082429aa2964;p=linux.git

arm64: dts: ti: k3-am64-main: Update TF-A load address to workaround USB DFU limitation

Due to a limitation for USB DFU boot mode, SPL load address has to be less
than  or equal to 0x70001000. So, load address of SPL and TF-A have been
moved to 0x70000000 and 0x701c0000 respectively, in U-Boot version 2021.10.

Therefore, update TF-A's location in the device tree node.
