2012-09-01tegra20: rename CONFIG_MACH_TEGRA_GENERICAllen Martin
Rename CONFIG_MACH_TEGRA_GENERIC to the less confusing CONFIG_TEGRA. The meaning of the config options is now: CONFIG_TEGRA - Any tegra chip CONFIG_TEGRA20 - A tegra20 family chip CONFIG_TEGRA30 - A tegra30 family chip (not added yet) Signed-off-by: Allen Martin <amartin@nvidia.com> Acked-by: Stephen Warren <swarren@wwwdotorg.org> Tested-by: Thierry Reding <thierry.reding@avionic-design.de> Signed-off-by: Tom Warren <twarren@nvidia.com>
2012-09-01tegra20: move tegra20 SoC code to arch/arm/cpu/tegra20-commonAllen Martin
In preparation for splitting out the armv4t code from tegra20, move the tegra20 SoC code to arch/arm/cpu/tegra20-common. This code will be compiled armv4t for the arm7tdmi and armv7 for the cortex A9.

2012-09-01ARM: add Raspberry Pi model B board, using BCM2835 SoCStephen Warren
The Raspberry Pi model B uses the BCM2835 SoC, has 256MB of RAM, contains an SMSC 9512 USB LAN/Hub chip, and various IO connectors. For more details, see http://www.raspberrypi.org/. Various portions (cache enable, MACH_TYPE setup, RAM size limit, stack relocation to top of RAM) extracted from work by: Oleksandr Tymoshenko <gonzo@bluezbox.com>. GPIO driver enablement by Vikram Narayanan <vikram186@gmail.com>. Signed-off-by: Stephen Warren <swarren@wwwdotorg.org> Acked-by: Tom Rini <trini@ti.com>
2012-09-01ARM: add basic support for the Broadcom BCM2835 SoCStephen Warren
This SoC is used in the Raspberry Pi, for example. For more details, see: http://www.broadcom.com/products/BCM2835 http://www.raspberrypi.org/wp-content/uploads/2012/02/BCM2835-ARM-Peripherals.pdf. Initial support is enough to boot to a serial console, execute a minimal set of U-Boot commands, download data over a serial port, and boot a Linux kernel. No storage or network drivers are implemented. GPIO driver originally by Vikram Narayanan <vikram186@gmail.com> with many fixes from myself. Signed-off-by: Stephen Warren <swarren@wwwdotorg.org>

2012-09-01arm: omap: Fix switching back to nandecc sw.Jeroen Hofstee
Orjan Friberg wrote at [1]: "For the beagleboard, ecc.size is not explicitly set when doing 'nandecc sw'. If it's not set for the NAND_ECC_SOFT case in nand_scan_tail, it's set to 256 bytes. When doing 'nandecc hw', ecc.size is set to 512 bytes. Hence, when changing back to 'nandecc sw' ecc.size remains at 512 bytes and suddenly the format has changed." No patch has been submitted and the issue was still present. This patch adds the mentioned solution. Tested on a tam3517 board.

2012-09-01davinci: enbw_cmc: change switch init behaviourHeiko Schocher
change the behaviour of switch initialization: - rename "pwl" to "lan" in hwconfig parameter "lan" = port 1 with phy addr 2 "lmn" = port 2 with phy addr 3 - if we have a valid switch config file in flash, do not evaluate the settings in the hwconfig "lan" or "lmn" subcommand. - if we have no valid switch config file in flash, start the switch with default values, if we have a "lan" or a "lmn" hwconfig subcommand. If no "lan" or "lmn" is found in hwconfig, do nothing with the switch. Signed-off-by: Heiko Schocher <hs@denx.de>
2012-09-01am33xx evm: Update secure_emif_sdram_config during ddr initSatyanarayana, Sandhya
This patch updates secure_emif_sdram_config with the same value written to sdram_config during ddr3 initialization. During suspend/resume, this value is copied into sdram_config. With this, a write to sdram_config at the end of resume sequence which triggers an init sequence can be avoided. Without this register write in place, the DDR_RESET line goes low for a few cycles during resume which is a violation of the JEDEC spec.

Make the lowlevel_init function that these platforms have which just sets up the stack and calls a C function available to all armv7 platforms. As part of this we change some of the macros that are used to be more clear. Previously (except for am335x evm) we had been setting CONFIG_SYS_INIT_SP_ADDR to a series of new defines that are equivalent to simply referencing NON_SECURE_SRAM_END. On am335x evm we should have been doing this initially and do now. Cc: Sricharan R <r.sricharan@ti.com> Tested-by: Allen Martin <amartin@nvidia.com> Signed-off-by: Tom Rini <trini@ti.com>
