Therefore, in order to make RO metadata cache fit into CBFS_MCACHE, enlarge it from 8K to 16K. Adjust the memlayout by decreasing the DRAM_INIT_CODE from 196K to 184K (only 160K needed for now), and moving VBOOT2_WORK region to L2C. Also shuffle the regions in SRAM with better comments.

2022-05-02soc/mediatek/mt8186: Prevent early USB wakeupRex-BC Chen
The MT8186 platform fails to suspend due to premature wakeup by USB. In MT8186, we use low level latch to keep USB wakeup signal. However, hardware could latch a wrong signal if it debounces more than one time. As a result, it would enable wakeup function too early. To prevent this issue, we do the following modification: - Delay about 100 us to enable wakeup function in kernel drivers [1]. - To guarantee 100 us is enough, we need to disable the USB debounce by default in coreboot. According to section register 0x404 and 0x420 in "(CODA) MT8169_PERICFG_REG.xls" which is only for MediaTek internal use: The current default value of debounce register for MT8186 USB IP0 and IP1 is incorrect. The reason we add in coreboot is that the default value should be correct when SoC is booting up. This modification is only for MT8186. The subsequent SoCs will adjust the wakeup function to correct register value by default.
