This commit add initial support for Freescale (NXP) P2020RDB Hardware: SoC: P2020 2x1GHz DRAM: 512-1GB DDR3 2 + 4 GBE (2 separate ports and four in VSC7385) Flash: 16MB NOR, 32MB NAND, 16MB SPI-NOR PCIE x1 and mPCIE x1 SD Reader Interfaces: GBE RJ45 x6 USB2.0 x1 UART x2 I2C x2 JTAG x1 SD x1 PCIE x2 (PCIE and mPCIE) Flash instructions: Place sysupgrade image to 0x80000 address in NOR. Eg. (no brakelines in setenv command): setenv 'firmware_flash tftpboot $loadaddr $firmwarefile; protect off $norfdtaddr +$filesize; erase $norfdtaddr +$filesize; cp.b $loadaddr $norfdtaddr $filesize; protect on $norfdtaddr +$filesize; cmp.b $loadaddr $norfdtaddr $filesize' setenv firmwarefile firmware.bin run firmware_flash Boot (no brakeline in setenv command): setenv bootcmd 'setenv bootargs root=/dev/mtdblock3 rw console=$consoledev, $baudrate rootfstype=squashfs $othbootargs; bootm $norfdtaddr' saveenv boot Known issues: -Switch is unmanaged (VSC 7385 is connected via eLBC, driver uses SPI) -No SD reader support Signed-off-by: Pawel Dembicki <paweldembicki@gmail.com> Signed-off-by: Christian Lamparter <chunkeey@gmail.com> [refreshed patches]
