From 5de6aed42c3519f819b913a8b218adb5ea827872 Mon Sep 17 00:00:00 2001 From: Pawel Dembicki Date: Sun, 30 Dec 2018 07:38:45 +0000 Subject: mpc85xx: add support for Freescale (NXP) P2020RDB 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 Signed-off-by: Christian Lamparter [refreshed patches] --- ...85xx-change-P2020RDB-dts-file-for-OpenWRT.patch | 170 +++++++++++++++++++++ 1 file changed, 170 insertions(+) create mode 100644 target/linux/mpc85xx/patches-4.19/104-powerpc-mpc85xx-change-P2020RDB-dts-file-for-OpenWRT.patch (limited to 'target/linux/mpc85xx/patches-4.19/104-powerpc-mpc85xx-change-P2020RDB-dts-file-for-OpenWRT.patch') diff --git a/target/linux/mpc85xx/patches-4.19/104-powerpc-mpc85xx-change-P2020RDB-dts-file-for-OpenWRT.patch b/target/linux/mpc85xx/patches-4.19/104-powerpc-mpc85xx-change-P2020RDB-dts-file-for-OpenWRT.patch new file mode 100644 index 0000000000..39c72314b8 --- /dev/null +++ b/target/linux/mpc85xx/patches-4.19/104-powerpc-mpc85xx-change-P2020RDB-dts-file-for-OpenWRT.patch @@ -0,0 +1,170 @@ +From 93514afd769c305182beeed1f9c4c46235879ef8 Mon Sep 17 00:00:00 2001 +From: Pawel Dembicki +Date: Sun, 30 Dec 2018 23:24:41 +0100 +Subject: [PATCH] powerpc: mpc85xx: change P2020RDB dts file for OpenWRT + +This patch apply chages for OpenWRT in P2020RDB +dts file. + +Signed-off-by: Pawel Dembicki +--- + arch/powerpc/boot/dts/fsl/p2020rdb.dts | 98 +++++++++++++++++--------- + 1 file changed, 63 insertions(+), 35 deletions(-) + +--- a/arch/powerpc/boot/dts/fsl/p2020rdb.dts ++++ b/arch/powerpc/boot/dts/fsl/p2020rdb.dts +@@ -2,6 +2,7 @@ + * P2020 RDB Device Tree Source + * + * Copyright 2009-2012 Freescale Semiconductor Inc. ++ * Copyright 2018 Pawel Dembicki + * + * This program is free software;
