2012-02-12tegra: Use funcmux for MMC on tamontenSimon Glass
Use the new funcmux_select() feature to set up the MMC pin mux. Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Tom Warren <twarren@nvidia.com>
2012-02-12tegra: Add SDMMC support to funcmuxSimon Glass
This adds support for SDMMC ports to the funcmux. Only one option is supported: FUNCMUXO_SDMMC_8BIT which selects an 8-bit wide SDIO interface where available. Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Tom Warren <twarren@nvidia.com>
2012-02-12tegra: Add I2C support to funcmuxSimon Glass
Add support to funcmux for selecting I2C functions and programming the pinmux appropriately. Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Tom Warren <twarren@nvidia.com>
2012-02-12tegra: Add enum to select from available funcmux configsSimon Glass
We want to give a name to each available funcmux config. For now we just use the pin group names (even through it is verbose) since there seems to be nothing better. Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Tom Warren <twarren@nvidia.com>
2012-02-12tegra: Adjust funcmux config test to permit expansionSimon Glass
We want to support config options other than zero, so move the test to the end to allow intermediate code to OK such a config. Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Tom Warren <twarren@nvidia.com>
2012-02-12tegra2: Add support for Compal Paz00 (Toshiba AC100)Stephen Warren
The Toshiba AC100 (Compal code-name Paz00, aka Dynabook AZ) is a netbook derived from the NVIDIA Tegra Harmony reference board. It ships with Android, but is often repurposed to run Linux. This patch adds just enough support to get a U-Boot serial console, and the ability access built-in eMMC and the external SD slot. v2: * Rebased on latest HEAD, incorporated changes made to other board files. * Moved board files from board/nvidia to board/compal. * Switched to correct odmdata value. This required add the previous patch to fix U-Boot's interpretation of the odmdata RAM size field. * Removed nvmem= from default Linux kernel command-line; no drivers use the reserved memory yet, so there's no point reserving it.

2012-02-12tegra2: Fix default RAM size selection in odmdataStephen Warren
A value of 0 in the odmdata RAM size field means default, which is 512MB not 1GB. Fix this.

2012-02-12tegra2: Fix conflicting pinmux for UARTAStephen Warren
Tegra appears to boot with function UARTA pre-selected on mux group SDB. If two mux groups are both set to the same function, it's unclear which group's pins drive the RX signals into the HW module. For UARTA, SDB certainly overrides group IRTX in practice. To solve this, configure some alternative function on SDB to avoid the conflict. Also, tri-state the group to avoid driving any signal onto it until we know what's connected.

2012-02-09* Fix: watchdog timed out, if flash blank (0xFF) blocksJens Scharsig (BuS Elektronik)
The current implementation of cfi_flash uses udelay to reset watchdog. If several blocks are blank (0xff filled) the watchdog timed out. The reason is, udelay is never called, if flash device is ready to fast. e.g. mw.w $(copy_addr) FFFF 10000;cp.b $(copy_addr) 10880000 20000 -> watchdog timed out mw.w $(copy_addr) 0000 10000;cp.b $(copy_addr) 10880000 20000 -> watchdog not timed out This patch adds an extra watchdog reset in front of flash ready check.

2012-01-26nand/fsl_elbc: Convert to self-initScott Wood
This driver doesn't yet make use of the added flexibility (not that that should stop anyone from converting...), but it will with the in-progress hack to support 4k-page NAND. Signed-off-by: Scott Wood <scottwood@freescale.com>
2012-01-26nand: Introduce CONFIG_SYS_NAND_SELF_INITScott Wood
This allows a driver to run code between nand_scan_ident() and nand_scan_tail(), among other things. See the additions to doc/README.nand for details. To allow a gradual transition, Boards that don't set CONFIG_SYS_NAND_SELF_INIT will still be initialized the old way, but new drivers should not require this, and existing drivers should be converted when convenient.

2012-01-26nand_spl: store ecc data on the stackScott Wood
Adapt the following patch from spl to nand_spl: Author: Stefano Babic <sbabic@denx.de> Date: Thu Dec 15 10:55:37 2011 +0100 nand_spl_simple: store ecc data on the stack Currently nand_spl_simple puts it's temp data at 0x10000 offset in SDRAM which is likely to contain already loaded data. The patch saves the oob data and the ecc on the stack replacing the fixed address in RAM. Signed-off-by: Stefano Babic <sbabic@denx.de> CC: Ilya Yanok <yanok@emcraft.com> CC: Scott Wood <scottwood@freescale.com> CC: Tom Rini <tom.rini@gmail.com> CC: Simon Schwarz <simonschwarzcor@googlemail.com> CC: Wolfgang Denk <wd@denx.de> Signed-off-by: Scott Wood <scottwood@freescale.com> While nand_spl is on its way out, in favor of spl, there are still many boards using it, and conversions are gradual. This allows us to get rid of CONFIG_SYS_NAND_ECCSTEPS and CONFIG_SYS_NAND_ECCTOTAL now, which would otherwise be likely to linger unreferenced after a conversion. It also eliminates a temporary error in the hawkboard_nand build, since the spl version of the patch removed ECCSTEPS/TOTAL from hawkboard.h, but the spl conversion is pending (and may be merged via a different tree).

2012-01-16drivers/i2c/omap24xx_i2c.c: move all local variables to SRAMAndreas Müller
At old overo boards TWL4030 RTC irq is connected to gpio112. Unfortunately this pin is also used for revision detection. Therefore we need to send shut-up to TWL4030 to avoid reading wrong revision. In SPL this must be done before SDRAM is set up because the type of SDRAM is revision dependent. By this patch it is ensured that all variables used by omap24xx_i2c.c are located in SRAM.
