[U-Boot] [PATCH v4 02/17] arm: socfpga: Move firewall code to firewall file
Ley Foon Tan
ley.foon.tan at intel.com
Thu Sep 12 10:10:50 UTC 2019
Move firewall related code to new firewall.c, to share
code in Stratix 10 and Agilex.
SDMMC will transfer data to OCRAM in SPL. So, enable privilege for SDMMC
to allow DMA transfer to OCRAM.

v4:
- Move SYSMGR_DMA* to firewall.c
v3:
- Move SOCFPGA_FIREWALL_TCU to firewall.c
