* x86: Select stdio devices for corebootSimon Glass2012-11-30-0/+12

* x86: Add CBMEM console driver for corebootVadim Bendebury2012-11-30-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch builds upon the recently introduced CBMEM console feature of coreboot. CBMEM console uses a memry area allocated by coreboot to store the console output. The memory area has a certain structure, which allows to determine where the buffer is, the buffer size and the location of the pointer in the buffer. This allows different phases of the firmware (rom based coreboot, ram based coreboot, u-boot after relocation with this change) to keep adding text to the same buffer. Note that this patch introduces a new console driver and adds the driver to the list of drivers to be used for console output, i.e. it engages only after u-boot relocates. Usiong CBMEM console for capturing the pre-relocation console output will be done under a separate change. >From Linux, run the cbmem.py utility (which is a part of the coreboot package) to see the output, e.g.: vvvvvvvvvvvvvvvvv SCSI: AHCI 0001.0300 32 slots 6 ports ? Gbps 0xf impl SATA mode flags: 64bit ilck stag led pmp pio ... Magic signature found Kernel command line: "cros_secure quiet loglevel=1 console=tty2... ^^^^^^^^^^^^^^^^^ Note that the entire u-boot output fits into the buffer only if the coreboot log level is reduced from the most verbose. Ether the buffer size will have to be increased, or the coreboot verbosity permanently reduced. Signed-off-by: Vadim Bendebury <vbendeb@chromium.org> Signed-off-by: Simon Glass <sjg@chromium.org>

* | mmc: tegra: use bounce buffer APIsStephen Warren2012-11-27-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Tegra's MMC driver does DMA, and hence needs cache-aligned buffers. In some cases (e.g. user load commands) this cannot be guaranteed by callers of the MMC APIs. To solve this, modify the Tegra MMC driver to use the new bounce_buffer_*() APIs. Note: Ideally, all U-Boot code will always provide address- and size- aligned buffers, so a bounce buffer will only ever be needed for user- supplied buffers (e.g. load commands). Ensuring this removes the need for performance-sucking bounce buffer cache management and memcpy()s. The one known exception at present is the SCR buffer in sd_change_freq(), which is only 8 bytes long. Solving this requires enhancing struct mmc_data to know the difference between buffer size and transferred data size, or forcing all callers of mmc_send_cmd() to have allocated buffers using ALLOC_CACHE_ALIGN_BUFFER(), which while true in this case, is not enforced in any way at present, and so cannot be assumed by the core MMC code.

* | common: rework bouncebuf implementationStephen Warren2012-11-27-9/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current bouncebuf API requires all parameters to be passed to both bounce_buffer_start() and bounce_buffer_stop(). Modify the bouncebuf start function to accept a state structure as a parameter, and only require that state struct to be passed to the stop function. This simplifies usage of the bounce buffer by clients. Don't modify the data pointer, but rather store the temporary buffer in this state struct. The bouncebuf code ensures that client code can always use a single buffer pointer in the state structure, irrespective of whether a bounce buffer actually had to be allocated. Move cache management logic into the bounce buffer code, so that each client doesn't have to duplicate this. I believe there's no need to invalidate the buffer before a DMA operation, since flushing the cache should prevent any write-backs. Update the MXS MMC driver for this change.

| | | | | | | | | | | | | | | | | | | | | | | | If any driver ever needs to use the bounce buffer API, it always needs to use it.

| * powerpc/mpc85xx/p2020rdb-pca: Use L2 SRAM for SPL bootScott Wood2012-11-26-36/+33
| | | | | | | | | | | | | | | | | | | | | | | | This allows DDR configuration to be deferred to the final U-Boot image, which is able to make use of SPD data. The SPL itself cannot use SPD due to code size constraints. It previously used fixed register values for DDR configuration, and those values did not work on the p2020rdb-pca board I tested with. It's possible that different revisions of the board require different settings. Using SPD eliminates that problem.

| | * fdt: Add option to default to most compatible conf in a fit imageGabe Black2012-11-12-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When booting a fit image with multiple configurations, the user either has to specify which configuration to use explicitly, or there has to be a default defined which is chosen automatically. This change adds an option to change that behavior so that a configuration can be selected explicitly, or the configuration which has the device tree that claims to be compatible with the earliest item in U-Boot's device tree. In other words, if U-Boot claimed to be compatible with A, B, and then C, and the configurations claimed to be compatible with A, D and B, D and D, E, the first configuration, A, D, would be chosen. Both the first and second configurations match, but the first one matches a more specific entry in U-Boot's device tree. The order in the kernel's device tree is ignored.

As a consequense of this change USB_SPEED_* values don't correspond directly to EHCI speed encoding anymore, I've added necessary recoding in EHCI driver. Also there is no point to put speed into pipe anymore so it's removed and a bunch of host drivers fixed to look at usb_device->speed instead. Old usbdescriptors.h included is not removed as it seems to be used by old USB device code. This makes usb.h and usbdevice.h incompatible. Fortunately the only place that tries to include both are the old MUSB code and it needs usb.h only for USB_DMA_MINALIGN used in aligned attribute on musb_regs structure but this attribute seems to be unneeded (old MUSB code doesn't support any DMA at all).
