Hello Hung-Te Lin, Jianjun Wang, Yu-Ping Wu, build bot (Jenkins),
I'd like you to reexamine a change. Please visit
https://review.coreboot.org/c/coreboot/+/84117?usp=email
to look at the new patch set (#6).
Change subject: soc/mediatek: Add mtk_pcie_deassert_perst for early PCIe reset ......................................................................
soc/mediatek: Add mtk_pcie_deassert_perst for early PCIe reset
Even we assert PRSET# early to save the delay between PERST# assertion and de-assertion. MediaTek PCIe driver still takes 47ms waiting for PCIe link up. (1ms delay for each try)
``` [INFO ] mtk_pcie_domain_enable: PCIe link up success (47 tries) ```
Refactor common/pcie.c and add mtk_pcie_deassert_perst for early PCIe reset. So we can de-assert PERST# at early stage to improve the boot time.
