Boards based on the Altra SoC from vendors such as ADLINK are configured differently and require access to I2C buses not listed in Ac01.h. Fix this by expanding AC01_I2C_BASE_ADDRESS_LIST to contain the full set of buses available. Since this changes the indexing of the buses, update the Mt Jade files to match. Add a new PCD to contain the bus number of the RTC since this is different between Mt Jade and ADLINK's COM-HPC-ALT platform. Signed-off-by: Rebecca Cran <[email protected]>
Bump the I2C bus speed used for the IPMI SSIF link to the BMC from 100 to 400 kHz to match the requirement listed in Platform/Ampere/JadePkg/PlatformPortingGuide.md. Signed-off-by: Rebecca Cran <[email protected]>
