This means, that a special, stripped-down version of +U-Boot runs in the beginning. In the case of the A3M071 board, this +SPL U-Boot version is less than 16 KiB big. This SPL U-Boot can either +boot the OS (Linux) or a "real", full-blown U-Boot. This detection +on whether to boot Linux or U-Boot is done by using the "boot_os" +environment variable. If "boot_os" is set to "yes", Linux will be +loaded and booted from the SPL U-Boot version. Otherwise, the +full-blown U-Boot version will be loaded and run. + +Enabling Linux booting: +----------------------- +From U-Boot: +=> setenv boot_os yes +=> saveenv + +From Linux: +$ fw_setenv boot_os yes + +Enabling U-Boot booting: +------------------------ +From U-Boot: +=> setenv boot_os no +=> saveenv + +From Linux: +$ fw_setenv boot_os no + + +Preparing Linux image(s) for booting from SPL U-Boot: +----------------------------------------------------- +To boot the Linux kernel from the SPL, the DT blob (fdt) needs to get +prepard/patched first. U-Boot usually inserts some dynamic values into +the DT binary (blob), e.g. autodetected memory size, MAC addresses, +clocks speeds etc. To generate this patched DT blob, you can use +the following command: + +1. Load fdt blob to SDRAM: +=> tftp 1800000 a3m071/a3m071.dtb + +2. Set bootargs as desired for Linux booting (e.g. flash_mtd): +=> run mtdargs addip2 addtty + +3. Use "fdt" commands to patch the DT blob: +=> fdt addr 1800000 +=> fdt boardsetup +=> fdt chosen + +4. Display patched DT blob (optional): +=> fdt print + +5. Save fdt to NOR flash: +=> erase fc180000 fc07ffff +=> cp.b 1800000 fc180000 10000 + +All this can be integrated into an environment command: +=> setenv upd_fdt 'tftp 1800000 a3m071/a3m071.dtb;run mtdargs addip addtty; \ +	fdt addr 1800000;fdt boardsetup;fdt chosen;erase fc180000 fc07ffff; \ +	cp.b 1800000 fc180000 10000' +=> saveenv + +After this, only "run upd_fdt" needs to get called to load, patch +and save the DT blob into NOR flash. + +Additionally, the Linux kernel image has to be saved uncompressed in +its uImage file (and not gzip compressed). This can be done with this +command: + +$ mkimage -A ppc -O linux -T kernel -C none -a 0 -e 0 \ +	-n "Linux Kernel Image" -d vmlinux.bin uImage.uncompressed + +------------------------------------------------------------------------ +Stefan Roese, 2012-08-23 diff --git a/roms/u-boot/board/a3m071/a3m071.c b/roms/u-boot/board/a3m071/a3m071.c new file mode 100644 index 00000000..b96ba811 --- /dev/null +++ b/roms/u-boot/board/a3m071/a3m071.c @@ -0,0 +1,475 @@ +/* + * (C) Copyright 2003-2004 + * Wolfgang Denk, DENX Software Engineering, wd@denx.de. + * + * (C) Copyright 2004 + * Mark Jonas, Freescale Semiconductor, mark.jonas@motorola.com. + * + * (C) Copyright 2006 + * MicroSys GmbH + * + * Copyright 2012-2013 Stefan Roese <sr@denx.de> + * + * SPDX-License-Identifier:	GPL-2.0+ + */ + +#include <common.h> +#include <command.h> +#include <mpc5xxx.h> +#include <pci.h> +#include <miiphy.h> +#include <linux/compiler.h> +#include <asm/processor.h> +#include <asm/io.h> + +#ifdef CONFIG_A4M2K +#include "is46r16320d.h" +#else +#include "mt46v16m16-75.h" +#endif + +DECLARE_GLOBAL_DATA_PTR; + +#if !defined(CONFIG_SYS_RAMBOOT) && \ +	(defined(CONFIG_SPL) && defined(CONFIG_SPL_BUILD)) +static void sdram_start(int hi_addr) +{ +	long hi_addr_bit = hi_addr ? 0x01000000 : 0; +	long control = SDRAM_CONTROL | hi_addr_bit; + +	/* unlock mode register */ +	out_be32((void *)MPC5XXX_SDRAM_CTRL, control | 0x80000000); + +	/* precharge all banks */ +	out_be32((void *)MPC5XXX_SDRAM_CTRL, control | 0x80000002); + +#ifdef SDRAM_DDR +	/* set mode register: extended mode */ +	out_be32((void *)MPC5XXX_SDRAM_MODE, SDRAM_EMODE); + +	/* set mode register: reset DLL */ +	out_be32((void *)MPC5XXX_SDRAM_MODE, SDRAM_MODE | 0x04000000); +#endif + +	/* precharge all banks */ +	out_be32((void *)MPC5XXX_SDRAM_CTRL, control | 0x80000002); + +	/* auto refresh */ +	out_be32((void *)MPC5XXX_SDRAM_CTRL, control | 0x80000004); + +	/* set mode register */ +	out_be32((void *)MPC5XXX_SDRAM_MODE, SDRAM_MODE); + +	/* normal operation */ +	out_be32((void *)MPC5XXX_SDRAM_CTRL, control); + +	/* +	 * Wait a short while for the DLL to lock before accessing +	 * the SDRAM +	 */ +	udelay(100); +} +#endif + +/* + * ATTENTION: Although partially referenced initdram does NOT make real use + * use of CONFIG_SYS_SDRAM_BASE.
