  Mediatek SoC uses part of the L2 cache as SRAM before DRAM is ready.
  After DRAM is ready, we should invoke disable_l2c_sram to reconfigure
  the L2C SRAM as L2 cache.

- Configure DMA buffer in DRAM:
  Set DRAM DMA to be non-cacheable to load blob correctly.

a49460c6b6 soc/mediatek: pass access mode to the payload
Some eMMCs (for example, Kingston-EMMC64G-TX29-HP) may enter the ready
state by sending CMD1 twice. If it is in the ready state, then the
payload (for example, depthcharge) will not send CMD1, but the access
mode is only available from the response of CMD1.

Therefore, we need to pass the access mode to the payload by defining
the following types:

- MMC_STATUS_CMD1_READY: in ready state and access mode is byte mode.
- MMC_STATUS_CMD1_READY_HCS: in ready state and access mode is sector
  mode.

3c6b304084 soc/mediatek/mt8192: Enable thermal hardware reset
Under the current watchdog setting, the system will not reboot when the
temperature is too high. To enable thermal hardware reset, we need to
enable thermal control request and set it to reboot mode.

Note that because thermal throttle (by lowering cpu frequency) is
currently enabled, the thermal hardware reset shouldn't be triggered
under normal circumstances.

This feature is only for new hardware structure for thermal. Therefore,
we only need to apply it on MT8192/MT8195/MT8186.

This setting is based on thermal and watchdog section of MT8192

5841bf3ec4 soc/mediatek/mt8186: Prevent early USB wakeup
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.
