* tegra2: Enable data cacheSimon Glass2012-02-12-0/+8
| | | | | | | | | | | | This enables the data cache on Tegra2 boards. As discussed on the list, this is better off in the Tegra2 cpu code than in a particular vendor directory. We should be safe turning on the cache for all Tegra2 boards.

* tegra: mmc: Support operation with dcache enabledSimon Glass2012-02-12-0/+16
| | | | | | | | | | | When the data cache is enabled we must flush on write and invalidate on read. We also check that buffers are aligned to data cache lines boundaries. With recent work in U-Boot this should generally be the case but the warnings will catch problems.

* tegra2: Add support for Compal Paz00 (Toshiba AC100)Stephen Warren2012-02-12-0/+175
| | | | | | | | | | | | | | | | | | | | 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.

* tegra2: Fix conflicting pinmux for UARTAStephen Warren2012-02-12-0/+12
| | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

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).
