pieeprom-2026-10-15: 2712: Support peripheral access mailbox for axi perf monitoring (latest) - #902
Merged
Conversation
…perf monitoring (latest) * Support peripheral access mailbox for axi perf monitoring We support GET_PERIPH_REG and SET_PERIPH_REG on Pi0-4 to allow access to some, whitelisted, peripheral registers that the arm cannot acccess. See: raspberrypi/linux#7671 * splash_screen: Added rp1 support Previously ignored rp1 support due to no spi driver Now I've written a driver, I have tied the rp1 i2c and spi drivers into the splash screen. Requires a minor backwards compatible change to the splash binaries * 2712: mailbox for direct spi eeprom operations The rpi-spi-eeprom tool can use the mailbox to read, write and erase spi eeprom directly. Requires nospi10 in config.txt.
