2016-07-15sunxi: Use BROM stored boot_media value to determine our boot-sourceHans de Goede
Now that we know that the BROM stores a value indicating the boot-source at the beginning of SRAM, use that instead of trying to recreate the BROM's boot probing. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>

2016-07-15sunxi: FEL - Add the ability to recognize and auto-import uEnv-style dataBernhard Nortmann
The patch converts one of the "reserved" fields in the sunxi SPL header to a fel_uEnv_length entry. When booting over USB ("FEL mode"), this enables the sunxi-fel utility to pass the string length of uEnv.txt compatible data; at the same time requesting that this data be imported into the U-Boot environment. If parse_spl_header() in the sunxi board.c encounters a non-zero value in this header field, it will therefore call himport_r() to merge the string (lines) passed via FEL into the default settings. Environment vars can be changed this way even before U-Boot will attempt to autoboot - specifically, this also allows overriding "bootcmd". With fel_script_addr set and a zero fel_uEnv_length, U-Boot is safe to assume that data in .scr format (a mkimage-type script) was passed at fel_script_addr, and will handle it using the existing mechanism ("bootcmd_fel").

2016-07-15sunxi: Support booting from SPI flashSiarhei Siamashka
Allwinner devices support SPI flash as one of the possible bootable media type. The SPI flash chip needs to be connected to SPI0 pins (port C) to make this work. More information is available at: https://linux-sunxi.org/Bootable_SPI_flash This patch adds the initial support for booting from SPI flash. The existing SPI frameworks are not used in order to reduce the SPL code size. Right now the SPL size grows by ~370 bytes when CONFIG_SPL_SPI_SUNXI option is enabled. While there are no popular Allwinner devices with SPI flash at the moment, testing can be done using a SPI flash module (it can be bought for ~2$ on ebay) and jumper wires with the boards, which expose relevant pins on the expansion header. The SPI flash chips themselves are very cheap (some prices are even listed as low as 4 cents) and should not cost much if somebody decides to design a development board with an SPI flash chip soldered on the PCB. Another nice feature of the SPI flash is that it can be safely accessed in a device-independent way (since we know that the boot ROM is already probing these pins during the boot time). And if, for example, Olimex boards opted to use SPI flash instead of EEPROM, then they would have been able to have U-Boot installed in the SPI flash now and boot the rest of the system from the SATA hard drive. Hopefully we may see new interesting Allwinner based development boards in the future, now that the software support for the SPI flash is in a better shape :-) Testing can be done by enabling the CONFIG_SPL_SPI_SUNXI option in a board defconfig, then building U-Boot and finally flashing the resulting u-boot-sunxi-with-spl.bin binary over USB OTG with a help of the sunxi-fel tool: sunxi-fel spiflash-write 0 u-boot-sunxi-with-spl.bin The device needs to be switched into FEL (USB recovery) mode first. The most suitable boards for testing are Orange Pi PC and Pine64. Because these boards are cheap, have no built-in NAND/eMMC and expose SPI0 pins on the Raspberry Pi compatible expansion header. The A13-OLinuXino-Micro board also can be used.

For A53, data coherency is enabled only when the CPUECTLR.SMPEN bit is set. The SMPEN bit should be set before enabling the data cache. If not enabled, the cache is not coherent with other cores and data corruption could occur. For A57/A72, SMPEN bit enables the processor to receive instruction cache and TLB maintenance operations broadcast from other processors in the cluster. This bit should be set before enabling the caches and MMU, or performing any cache and TLB maintenance operations.
