* tegra: usb: Fix device enumeration problem of USB1Jim Lin2012-07-09-1/+18
| | | | | | | | | | | | | | A known hardware issue of USB1 port where bit 1 (connect status change) of PORTSC register will be set after issuing Port Reset (like "usb reset" in u-boot command line). This will be treated as an error and stops later device enumeration. Therefore we clear that bit after Port Reset in order to proceed later device enumeration.

* tegra: trimslice: set up serial flash pinmuxStephen Warren2012-07-09-0/+5
| | | | | | | | | | | When Trimslice is booted from serial flash, the boot ROM does this, so U-Boot doesn't need to. However, booting from the SD slot for recovery purposes, the boot ROM does not set up the pinmux for serial flash. Add code to U-Boot to set this up, so that an SD-based recovery U-Boot image can upgrade the U-Boot in serial flash.

* tegra: bootcmd: start USB only when neededStephen Warren2012-07-09-3/+11
| | | | | | | | | | Instead of initializing USB as soon as bootcmd is executed, defer it until the first boot device that (potentially in the case of network) uses USB is scanned. This avoids initializing USB when booting from MMC, so speeds that up. Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Tom Warren <twarren@nvidia.com>
* tegra: bootcmd enhancementsStephen Warren2012-07-09-30/+52
| | | | | | | | | | | | | | | | | | | | | | | Place the list of searched boot devices, file-system types, boot file locations/prefixes, and boot script names into variables. This allows the user to override them directly (e.g. to change boot order, or select the specific values they use) without having to edit the main bootcmd and script_boot variables. The default boot order is changed from USB, MMC, DHCP to MMC, USB, DHCP. This speeds up the typical MMC boot case. People who want USB boot can now edit variable boot_targets appropriately. Also, reformat BOOTCMDS_COMMON to fit within 80 columns. Potential future enhancements might be: * Allow boards to specify which of bootcmd_mmc0/... should be defined, based on the HW they contain. * Allow boards to influence the order that the boot targets are added into the boot_targets variable.

* tegra: add enterrcm commandStephen Warren2012-07-09-0/+67
| | | | | | | | | | | | | | | | | Tegra's boot ROM supports a mode whereby code may be downloaded and flash programmed over a USB connection. On dev boards, this is typically entered by holding down a "force recovery" button and resetting the CPU. However, not all boards have such a button (one example is the Compulab Trimslice), so a method to enter RCM from software is useful. This change implements the command "enterrcm" to do this, and enables it for all Tegra boards by default. Even on boards other than Trimslice, controlling this over a UART may be useful, e.g. to allow simple remote control without the need for mechanical button actuators, or hooking up relays/... to the button.

* fdt: send all dtc output to stderrStephen Warren2012-07-09-1/+1
| | | | | | | | | | | | | | | | | | | | | | Commit 896bbb5 "fdt: avoid bad MAKEALL status" added logic to capture the result code from dtc by echoing $? to stdout and capturing it using $(). However, dtc emits some diagnostics to stderr and some to stdout. The diagnostics send to stdout ended up getting captured via $() rather than being echo'd to the user. This caused those diagnostics to be passed to the exit command, which would then fail with the following cryptic error message: /bin/sh: line 1: exit: too many arguments Solve this by redirecting all dtc output to stderr so that $() does not capture it. This allows the user to see the actual error message from dtc.

In the above sequence dcache_disable() flushes, invalidates the caches and turns off the mmu. But after it cleanups the cache and before the mmu is disabled there is a cp_delay() function which has STR instruction. On certain cores like the cortex-a15, cache hit and a write can happen to a cache line even when the dcache is disabled. So the above mentioned STR instruction creates a dirty entry after cleaning. The mmu gets disabled after this. 2) invalidate_dcache_all invalidates the cache lines. Again on cores like cortex-a15, invalidate instruction flushes the dirty line as well. So some times the dirty line from sequence 1 can corrupt the memory resulting in a crash. Fixing this by moving the get_cr() and cp_delay() calls before cleaning up the cache, thus avoiding the dirty entry. Signed-off-by: R Sricharan <r.sricharan@ti.com>

| * arm: Don't use printf() in SPL buildsSimon Glass2012-07-07-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | raise() likes to call printf() if it is available, but in SPL builds it either is not available, or adds a large chunk to the resulting image size. So don't call it even if it is available. This change reduces SPL size from 10KB to 6.3KB on hawkboard, for example, using generic relocation.

| * net: Multiple updates/enhancements to designware.cStefan Roese2012-07-07-69/+51
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds the following changes to designware ethernet driver found on the ST SPEAr SoC: - Don't init MAC & PHY upon startup. This causes a delay, waiting for the auto negotiation to complete. And we don't want this delay to always happen. Especially not on platforms where ethernet is not used at all (e.g. booting via flash). Instead postpone the MAC / PHY configuration to the stage, where ethernet is first used. - Add possibility for board specific PHY init code. This is needed for example on the X600 board, where the Vitesse PHY needs to be configured for GMII mode. This board specific PHY init is done via the function designware_board_phy_init(). And this driver now adds a weak default which can be overridden by board code. - Use common functions miiphy_speed() & miiphy_duplex() to read link status from PHY. - Print status and progress of auto negotiation. - Print link status (speed, dupex) upon first usage.
