* mtd: nand: davinci: add opportunity to write keystone U-boot imageKhoronzhuk, Ivan2014-07-25-1/+199
| | | | | | | | | | | | | | | | | | | | | | | | The Keystone SoCs use the same NAND driver as Davinci. This patch adds opportunity to write Keystone U-boot image to NAND device using appropriate RBL ECC layout. This is needed only if RBL boots U-boot from NAND device and that's supposed that raw u-boot partition is used only for writing image. The main problem is that default Davinci ECC layout is different from Keystone RBL layout. To read U-boot image the RBL needs that image was written using RBL ECC layout. The BBT table is written using default Davinci layout and has to be updated using one. The BBT can be updated only while erasing chip or by forced bad block assigning, so erase function has to use native ecc layout in order to be able to write BBT correctly. So if we're writing to NAND U-boot address we use RBL layout for others we use default ECC layout. Also remove definition for CONFIG_CMD_NAND_ECCLAYOUT as there is no reasons to use ECC layout commands. It was added by mistake. Signed-off-by: Ivan Khoronzhuk <ivan.khoronzhuk@ti.com>

| | | | | | | | | | | | | | | | In current gpio_set_value() implementation, it always sets the gpio control bit no matter the value argument is 0 or 1. Thus the GPIOs never set to low. This patch fixes this bug. The address bus is used as a mask on read/write operations, so that independent software drivers can set their GPIO bits without affecting any other pins in a single write operation. Thus we don't need a read-modify-write to update the register.

* arm: Add support for semihosting for armv8 fastmodel targets.Darwin Rambo2014-07-03-12/+462
| | | | | | | | | | | | | | | | | | | | | | The armv8 ARM Trusted Firmware (ATF) can be used to load various ATF images and u-boot, and does this for virtual platforms by using semihosting. This commit extends this idea by allowing u-boot to also use semihosting to load the kernel/ramdisk/dtb. This eliminates the need for a bootwrapper and produces a more realistic boot sequence with virtual models. Though the semihosting code is quite generic, support for armv7 in fastmodel is less useful due to the wide range of available silicon and the lack of a free armv7 fastmodel, so this change contains an untested armv7 placeholder for the service trap opcode. Please refer to doc/README.semihosting for a more detailed description of semihosting and how it is used with the armv8 virtual platforms.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During bootm/z, U-Boot relocates the DTB and initrd to high memory so they are out of the way of the kernel. On ARM at least, some parts of high memory are "highmem" and can't be accessed at early boot. To solve this, we need to restrict this relocation process to use lower parts of RAM that area accessible. For the DTB, an earlier patch of mine set CONFIG_SYS_BOOTMAPSZ. However, since some platforms have different restrictions on DTB and initrd location, that config option doesn't affect the initrd. We need to set the initrd_high environment variable to control the initrd relocation. Since we have carefully chosen the load addresses for the DTB and initrd (see comments in include/configs/tegraNNN-common.h re: values in MEM_LAYOUT_ENV_SETTINGS), we don't actually need any DTB or initrd relocation at all. Skipping relocation removes some redundant work. Hence, set both fdt_high and initrd_high to ffffffff which completely disables relocation. If the user does something unusual, such as using custom locations for the DTB/initrd load address or wanting to use DTB/initrd relocation for some reason, they can simply set these variables to custom values to override these environment defaults. With this change, cmd_sysboot works correctly for a filesystem created by the Fedora installer. Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Tom Warren <twarren@nvidia.com>

Adjust Tegra's default boot scripts to use the correct location. This change aligns Tegra's boot scripts with rpi_b.h and also the location that the Fedora installer actually puts the file.
