* rpi: add support for Raspberry Pi ZeroStephen Warren2015-12-05-0/+5
| | | | | | | For U-Boot's purposes, at present all we care about is ensuring there's a model table entry. Signed-off-by: Stephen Warren <swarren@wwwdotorg.org>
* rpi: fix revision scheme parsingStephen Warren2015-12-05-34/+53
| | | | | | | | | | The RPi has two different schemes for encoding board revision values. When adding RPi 2 support, I thought that the conflicting type field values were to be interpreted based on bcm2835-vs-bcm2836. In fact, the scheme bit determines the encoding. The RPi Zero uses the bcm2835 yet uses the new encoding scheme. Fix the code to cater for this correctly. Signed-off-by: Stephen Warren <swarren@wwwdotorg.org>
* rpi: get rid of BCM2835_BOARD_REV_* macrosStephen Warren2015-12-05-19/+23
| | | | | | | | | | | | | | There are two numbering schemes for the RPi revision values; old and new scheme. The values within each scheme overlap. Hence, it doesn't make sense to have absolute/global names for the revision IDs. Get rid of the names and just use the raw revision/type values to set up the array of per-revision data. This change makes most sense when coupled with the next change. However, it's split out so that the mechanical cut/paste is separate from the logic changes for easier review and problem bisection.

| | | | | | | | | | | | Add CONFIG_ENV_VARS_UBOOT_RUNTIME_CONFIG support and enable it to set 'board_rev' and 'board_name' envs. 'board_rev' can be used in scripts to determine what board we are running on and 'board_name' for pretty printing.

| | | | | | | | Seen this one in the wild. Is labelled "Raspberry Pi Model A+ V1.1, (C) Raspberry Pi 2014". A standard A+ board, much like the one with version 0x12, didn't notice any differencies. Signed-off-by: Lubomir Rintel <lkundrak@v3.sk>
* Move ALLOC_CACHE_ALIGN_BUFFER() to the new memalign.h headerSimon Glass2015-09-11-0/+1
| | | | | | | Now that we have a new header file for cache-aligned allocation, we should move the stack-based allocation macro there also. Signed-off-by: Simon Glass <sjg@chromium.org>
* ARM: bcm283x: Allocate all mailbox buffers cacheline alignedAlexander Stein2015-08-12-5/+5
| | | | | | | | | | The mailbox buffer is required to be at least 16 bytes aligned, but for cache invalidation and/or flush it needs to be cacheline aligned. Use ALLOC_CACHE_ALIGN_BUFFER for all mailbox buffer allocations.

* ARM: bcm283x: merge BCM2835/BCM2836 directories into mach-bcm283xMasahiro Yamada2015-03-28-30/+0
| | | | | | | | | | BCM2835 (used on Raspberry Pi) and BCM2836 (used on Raspberry Pi 2) are similar enough. One of the biggest differences is the ARM processor. It is reasonable to collect the source files into a single place, arch/arm/mach-bcm283x/.

* ARM: rpi: fix RPi1 board rev detection for warranty bitStephen Warren2015-03-24-0/+7
| | | | | | | | | Apparently the firmware's board rev response includes both the board revision and some other data even on the RPi1. In particular, the "warranty bit" is bit 24. We need to mask that out when looking up the board ID. Signed-off-by: Stephen Warren <swarren@wwwdotorg.org>

* ARM: rpi: consolidate board rev error checkingStephen Warren2014-12-29-7/+9
| | | | | | | | | Create a fake model table entry with default values, so we can error check the board rev value once when querying it from the firmware, rather than error-checking for invalid board rev values every time the model table is used. Signed-off-by: Stephen Warren <swarren@wwwdotorg.org>

* ARM: rpi: only set usbethaddr on relevant systemsStephen Warren2014-12-29-0/+17
| | | | | | | | | Model A and CM RPis don't have an on-board USB Ethernet device. Hence, there's no point setting $usbethaddr based on the device fuses. Use the model detection code to gate this. Note that the fuses are actually programmed even on those devices though. Signed-off-by: Stephen Warren <swarren@wwwdotorg.org>

* ARM: rpi_b: detect board revisionStephen Warren2014-12-08-3/+119
| | | | | | | | | | | | | | | | | | | | | | | | Detect the board revision early during boot, and print the decoded model name. Eventually, this information can be used for tasks such as: - Allowing/preventing USB device mode; some models have a USB device on- board so only host mode makes sense. Others connect the SoC directly to the USB connector, so device-mode might make sense. - The on-board USB hub/Ethernet requires different GPIOs to enable it, although luckily the default appears to be fine so far. - The compute module contains an on-board eMMC device, so we could store the environment there. Other models use an SD card and so don't support saving the environment (unless we store it in a file on the FAT boot partition...) Set $fdtfile based on this information. At present, the mainline Linux kernel doesn't contain a separate DTB for most models, but I hope that will change soon.

* fdt: Allow ft_board_setup() to report failureSimon Glass2014-11-21-1/+3
| | | | | | | | | | | | | | | | | | This function can fail if the device tree runs out of space. Rather than silently booting with an incomplete device tree, allow the failure to be detected. Unfortunately this involves changing a lot of places in the code. I have not changed behvaiour to return an error where one is not currently returned, to avoid unexpected breakage. Eventually it would be nice to allow boards to register functions to be called to update the device tree. This would avoid all the many functions to do this. However it's not clear yet if this should be done using driver model or with a linker list. This work is left for later.

* kconfig: arm: introduce symbol for ARM CPUsGeorges Savoundararadj2014-10-29-3/+0
| | | | | | | | | | | | | | | | | This commit introduces a Kconfig symbol for each ARM CPU: CPU_ARM720T, CPU_ARM920T, CPU_ARM926EJS, CPU_ARM946ES, CPU_ARM1136, CPU_ARM1176, CPU_V7, CPU_PXA, CPU_SA1100. Also, it adds the CPU feature Kconfig symbol HAS_VBAR which is selected for CPU_ARM1176 and CPU_V7. For each target, the corresponding CPU is selected and the definition of SYS_CPU in the corresponding Kconfig file is removed. Also, it removes redundant "string" type in some Kconfig files.

* Add board MAINTAINERS filesMasahiro Yamada2014-07-30-0/+6
| | | | | | | | | | | | | | | | | | | | We have switched to Kconfig and the boards.cfg file is going to be removed. We have to retrieve the board status and maintainers information from it. The MAINTAINERS format as in Linux Kernel would be nice because we can crib the scripts/get_maintainer.pl script. After some discussion, we chose to put a MAINTAINERS file under each board directory, not the top-level one because we want to collect relevant information for a board into a single place.

* kconfig: add board Kconfig and defconfig filesMasahiro Yamada2014-07-30-0/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | This commit adds: - arch/${ARCH}/Kconfig provide a menu to select target boards - board/${VENDOR}/${BOARD}/Kconfig or board/${BOARD}/Kconfig set CONFIG macros to the appropriate values for each board - configs/${TARGET_BOARD}_defconfig default setting of each board (This commit was automatically generated by a conversion script based on boards.cfg) In Linux Kernel, defconfig files are located under arch/${ARCH}/configs/ directory. It works in Linux Kernel since ARCH is always given from the command line for cross compile. But in U-Boot, ARCH is not given from the command line. Which means we cannot know ARCH until the board configuration is done. That is why all the "*_defconfig" files should be gathered into a single directory ./configs/.

For SDHCI this isn't needed in practice, since the firmware already turned on the power in order to load U-Boot. However, it's best to be explicit. For USB, this is necessary, since the module isn't powered otherwise. This will allow the kernel USB driver to work. Signed-off-by: Stephen Warren <swarren@wwwdotorg.org>
