2019-01-24mediatek/mt8183: Move some initialization into mt8183_early_initYou-Cheng Syu
MT8183 only allows booting from eMMC, so we have to do eMMC emulation from an external source, for example EC, which makes the size of bootblock very important. This CL adds a new function mt8183_early_init, which includes all initializations that should be done in early stages. All mainboards using MT8183 should manually call it in either bootblock or verstage. BRANCH=none BUG=b:120588396 TEST=manually boot into kernel Change-Id: I35d7ab875395da913b967ae1f7b72359be3e744a Signed-off-by: You-Cheng Syu <youcheng@google.com> Reviewed-on: https://review.coreboot.org/c/31024 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Julius Werner <jwerner@chromium.org>
2018-07-27mediatek/mt8183: Remove unused MMU stuff from bootblockTristan Shieh
Since we move mtk_mmu_init() from bootblock to decompressor, we don't need to build mmu_opertations.c in bootblock and we don't need to include <soc/mmu_operations.h> in bootblock.c. BUG=b:80501386 TEST=manually flashed into kukui and boots into romstage.

2018-07-26mediatek/mt8183: Enable bootblock self-decompressionHung-Te Lin
MT8183 only allows booting from eMMC, so we have to do eMMC emulation from an external source, for example EC, which makes the size of bootblock very important. A fully functional bootblock (that can boot into verstage or romstage) is about 38000 bytes. If self decompression (CONFIG_COMPRESS_BOOTBLOCK) is enabled, only 25088 (66%) bytes are needed. Inspired from crosreview.com/1070018. BUG=b:80501386 TEST=manually flashed into kukui and boots into romstage.

Enable MMU in bootblock for performance, link common code to provide mtk_mmu_after_dram() to update MMU table in romstage after dram ready, implement mtk_soc_disable_l2c_sram(), and call mtk_mmu_disable_l2c_sram() to turn off L2C sram in ramstage.
