Hello,
This is v3 of the patchset that adds all the SPL code that is necessary to support the SoCFPGA platform. For v3, here are the changes:
- Remove gdata - Remove s_init - Remove socfpga lowlevel_init.S - Use common u-boot-spl.lds - Properly use CONFIG_SPL_TEXT_BASE so we don't have to add an .sram section
I have pushed a branch to git://git.rocketboards.org/u-boot-socfpga-next.git socfpga_for_next_spl_v3 for testing and reviewing.
Rebased to 2015.04-rc4.
Thanks,
