Correction: I'd wrongly inferred from the testing done on OMAP5 that the series would build fine. However it appears that for targets omap4_sdp4430, omap4_panda and omap5_evm, patch 2/2 has warnings: hwinit-common.c: In function 'dram_bank_mmu_setup': hwinit-common.c:279:3: warning: implicit declaration of function 'set_section_dcache' [-Wimplicit-function-declaration] Luckily, I had not committed to the git repo yet. R Sicharan, can you please check and fix this warning?
