commit 32a7a81c7e7a5ae51cdebf5fc02c51bc23b3f375 Author: Vadim Bendebury vbendeb@chromium.org Date: Tue Nov 11 20:14:47 2014 -0800
pistachio: modify memory layout
With the code now running on the FPGA board it makes sense to correct the memory layout definitions to match the actual hardware.
Note that the latest FPGA board firmware introduced support of the additional 128KB of SRAM (called GRAM) at base address of 0x9a000000.
These are still interim values, which will be tweaked when the actual bring up board is available.
BRANCH=none BUG=chrome-os-partner:31438 TEST=the code put into SPI NOR flash boots all the way to ramstage.
