Subject: vexpress64: support the Juno Development Platform
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=ffc103732c82faa945c85bbb7c5c34c30b6fac72;p=u-boot.git

vexpress64: support the Juno Development Platform

The Juno Development Platform is a physical Versatile Express
device with some differences from the emulated semihosting
models. The main difference is that the system is split in
a SoC and an FPGA where the SoC hosts the serial ports at
totally different adresses.
