From 18c0144542a73a735ab55f0f51e4a5a255e92c1a Mon Sep 17 00:00:00 2001 From: Prabhakar Kushwaha Date: Tue, 8 Apr 2014 19:13:56 +0530 Subject: board/t104xrdb: Add support of NAND, SD, SPI boot for T104xRDB Add support of 2 stage NAND, SD, SPI boot loader using SPL framework. here, PBL initialise the internal SRAM and copy SPL(160KB). This further initialise DDR using SPD and environment and copy u-boot(768 KB) from NAND to DDR. Finally SPL transer control to u-boot. Initialise/create followings required for SPL framework - Add spl.c which defines board_init_f, board_init_r - update tlb and ddr accordingly Signed-off-by: Prabhakar Kushwaha Reviewed-by: York Sun --- board/freescale/t104xrdb/Makefile | 7 +- board/freescale/t104xrdb/README | 73 ++++++++++++++++++++ board/freescale/t104xrdb/ddr.c | 5 +- board/freescale/t104xrdb/spl.c | 122 +++++++++++++++++++++++++++++++++ board/freescale/t104xrdb/t1040_rcw.cfg | 7 ++ board/freescale/t104xrdb/t1042_rcw.cfg | 7 ++ board/freescale/t104xrdb/t104x_pbi.cfg | 26 +++++++ board/freescale/t104xrdb/tlb.c | 12 ++++ 8 files changed, 256 insertions(+), 3 deletions(-) create mode 100644 board/freescale/t104xrdb/spl.c create mode 100644 board/freescale/t104xrdb/t1040_rcw.cfg create mode 100644 board/freescale/t104xrdb/t1042_rcw.cfg create mode 100644 board/freescale/t104xrdb/t104x_pbi.cfg (limited to 'board/freescale/t104xrdb') diff --git a/board/freescale/t104xrdb/Makefile b/board/freescale/t104xrdb/Makefile index 7e7bfb1c5b..6cd304cce9 100644 --- a/board/freescale/t104xrdb/Makefile +++ b/board/freescale/t104xrdb/Makefile @@ -4,11 +4,14 @@ # SPDX-License-Identifier: GPL-2.0+ # - +ifdef CONFIG_SPL_BUILD +obj-y += spl.o +else obj-y += t104xrdb.o obj-y += cpld.o -obj-y += ddr.o obj-y += eth.o obj-$(CONFIG_PCI) += pci.o +endif +obj-y += ddr.o obj-y += law.o obj-y += tlb.o diff --git a/board/freescale/t104xrdb/README b/board/freescale/t104xrdb/README index 1da52bb0b0..cdbe1fafd9 100644 --- a/board/freescale/t104xrdb/README +++ b/board/freescale/t104xrdb/README @@ -198,3 +198,76 @@ The below commands apply to the board 2.To change from vbank4 to vbank0 => qixis reset (it will boot using vbank0) + +NAND boot with 2 Stage boot loader +---------------------------------- +PBL initialise the internal SRAM and copy SPL(160KB) in SRAM. +SPL further initialise DDR using SPD and environment variables and copy +u-boot(768 KB) from flash to DDR. +Finally SPL transer control to u-boot for futher booting. + +SPL has following features: + - Executes within 256K + - No relocation required + + Run time view of SPL framework during boot :- + ----------------------------------------------- + Area | Address | +----------------------------------------------- + Secure boot | 0xFFFC0000 (32KB) | + headers | | + ----------------------------------------------- + GD, BD | 0xFFFC8000 (4KB) | + ----------------------------------------------- + ENV | 0xFFFC9000 (8KB) | + ----------------------------------------------- + HEAP | 0xFFFCB000 (30KB) | + ----------------------------------------------- + STACK | 0xFFFD8000 (22KB) | + ----------------------------------------------- + U-boot SPL | 0xFFFD8000 (160KB) | + ----------------------------------------------- + +NAND Flash memory Map on T104xRDB +------------------------------------------ + Start End Definition Size +0x000000 0x0FFFFF u-boot 1MB +0x180000 0x19FFFF u-boot env 128KB +0x280000 0x29FFFF FMAN Ucode 128KB +0x380000 0x39FFFF QE Firmware 128KB + +SD Card memory Map on T104xRDB +------------------------------------------ + Block #blocks Definition Size +0x008 2048 u-boot 1MB +0x800 0024 u-boot env 8KB +0x820 0256 FMAN Ucode 128KB +0x920 0256 QE Firmware 128KB + +SPI Flash memory Map on T104xRDB +------------------------------------------ + Start End Definition Size +0x000000 0x0FFFFF u-boot 1MB +0x100000 0x101FFF u-boot env 8KB +0x110000 0x12FFFF FMAN Ucode 128KB +0x130000 0x14FFFF QE Firmware 128KB + +Please note QE Firmware is only valid for T1040RDB + + +Switch Settings: (ON is 0, OFF is 1) +=============== +NAND boot SW setting: +SW1: 10001000 +SW2: 00111001 +SW3: 11110001 + +SPI boot SW setting: +SW1: 00100010 +SW2: 10111001 +SW3: 11100001 + +SD boot SW setting: +SW1: 00100000 +SW2: 00111001 +SW3: 11100001 diff --git a/board/freescale/t104xrdb/ddr.c b/board/freescale/t104xrdb/ddr.c index 57d0f9cfd8..34c9224adb 100644 --- a/board/freescale/t104xrdb/ddr.c +++ b/board/freescale/t104xrdb/ddr.c @@ -113,6 +113,7 @@ phys_size_t initdram(int board_type) { phys_size_t dram_size;
