The Raspberry Pi 3 contains a BCM2837 SoC. The BCM2837 is a BCM2836 with the CPU complex swapped out for a quad-core ARMv8. This can operate in 32- or 64-bit mode. 32-bit mode is the current default selected by the VideoCore firmware on the Raspberry Pi 3. This patch adds a 32-bit port of U-Boot for the Raspberry Pi 3. >From U-Boot's perspective, the only delta between the RPi 2 and RPi 3 is a change in usage of the SoC UARTs. On all previous Pis, the PL011 was the only UART in use. The Raspberry Pi 3 adds a Bluetooth module which uses a UART to connect to the SoC. By default, the PL011 is used for this purpose since it has larger FIFOs than the other "mini" UART. However, this can be configured via the VideoCore firmware's config.txt file. This patch hard-codes use of the mini UART in the RPi 3 port. If your system uses the PL011 UART for the console even on the RPi 3, please use the RPi 2 U-Boot port instead. A future change might determine which UART to use at run-time, thus allowing the RPi 2 and RPi 3 (32-bit) ports to be squashed together. The mini UART has some limitations. One externally visible issue in the BCM2837 integration is that the UART divides the SoC's "core clock" to generate the baud rate. The core clock is typically variable, and under control of the VideoCore firmware for thermal management reasons. If the VC FW does modify the core clock rate, UART communication will be corrupted since the baud rate will vary from the expected value. This was not an issue for the PL011 UART, since it is fed by a fixed 3MHz clock. To work around this, the VideoCore firmware can be told not to modify the SoC core clock. However, the only way this can happen and be thermally safe is to limit the core clock to a low/minimum frequency. This leaves performance on the table for use-cases that don't care about a UART console. Consequently, use of the mini UART console must be explicitly requested by entering the following line into config.txt: enable_uart=1 A recent version of the VC firmware is required to ensure that the mini UART is fully and correctly initialized by the VC FW; at least firmware.git 046effa13ebc "firmware: arm_loader: emmc clock depends on core clock See: https://github.com/raspberrypi/firmware/issues/572 ".

This allows U-Boot to known the name of the board. The existing rpi_2_defconfig can operate correctly on the Raspberry Pi 3 in 32-bit mode /if/ you have configured the firmware to use the PL011 UART as the console UART (the default is the mini UART). This requires two things: a) config.txt should contain dtoverlay=pi3-miniuart-bt b) You should run the following to tell the VC FW to process DT when booting, and copy u-boot.bin.img (rather than u-boot.bin) to the SD card as the kernel image: path/to/kernel/scripts/mkknlimg --dtok u-boot.bin u-boot.bin.img This works as of firmware.git commit 046effa13ebc "firmware: arm_loader: emmc clock depends on core clock See: https://github.com/raspberrypi/firmware/issues/572 ".

To simplify support for new SoCs, just use a constant filename for the unknown case. In practice this case shouldn't be hit anyway, so the filename isn't relevant, and certainly doesn't need to differentiate between SoCs. If a user has an as-yet-unknown board, they can override this value in the environment anyway. Signed-off-by:

Without programming these, we end up seeing lack of coherency on certain peripherals resulting in inexplicable failures (such as USB peripheral's DMA data not appearing on ARM etc and weird workarounds being done by drivers including cache flushes which tend to have system wide performance impact). By marking these segments as shared, we also ensure SoC wide coherency is enabled. Reported-by:

MSMC segment Privilege ID is not consistent accross the keystone2 SoCs. As the first step to ensure complete SoC wide coherency setup, lets refactor the macros to remove the #if-deffery around the code which obfuscates which IDs are actually enabled for which SoC. As a result of this change the PCIe configuration is moved after the msmc configuration is complete, but that should ideally have no functional impact. Signed-off-by:

Some parts of the sunxi code cast explicitly between u32 values and pointers.
