* spl: add RAM boot device only if it is actually definedStefan Agner2016-11-28-0/+2
| | | | | | | | | | | | Some devices (e.g. dra7xx) support loading to RAM using DFU without having direct boot from RAM support. Make sure the linker list does not contain BOOT_DEVICE_RAM if CONFIG_SPL_RAM_DEVICE is not enabled.

* spl: Make spl_boot_list a local variableSimon Glass2016-10-06-12/+12
| | | | | | | | | | | There is no need for this to be in the BSS region. By moving it we can delay use of BSS in SPL. This is useful for machines where the BSS region is not in writeable space. On 64-bit x86, SPL runs from SPI flash and it is easier to eliminate BSS use than link SPL to run with BSS at a particular cache-as-RAM (CAR) address.

| * sunxi: Support booting from SPI flashSiarhei Siamashka2016-07-15-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | dm: spl: Bind in all devices in SPL with of-platdataSimon Glass2016-07-14-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | When CONFIG_OF_PLATDATA is enabled, we cannot use the u-boot,dm-pre-reloc device tree property since the device tree is not available. However, dt-platdata.c only includes devices which would have been present in the device tree, and we can assume that all such devices are needed for SPL. If they were not needed, they would have been omitted to save space. So in this case, bind all devices regardless of the u-boot,dm-pre-reloc setting. This avoids needing to add a DM_FLAG_PRE_RELOC to every driver, thus affecting U-Boot proper also. Signed-off-by: Simon Glass <sjg@chromium.org>

| | | | | | | | | | | | | | | | | | As of gcc 5.2.1 for Thumb-1, it is not possible any more to assign gd from C code, as gd is mapped to r9, and r9 may now be saved in the prolog sequence, and restored in the epilog sequence, of any C functions. Therefore arch_setup_gd(), which is supposed to set r9, may actually have no effect, causing U-Boot to use a bad address to access GD. Fix this by never calling arch_setup_gd() for ARM, and instead setting r9 in arch/arm/lib/crt0.S, to the value returned by board_init_f_alloc_reserve().

When DRAM becomes available we may switch the stack from SRAM to DRAM to give use more room. This commit adds support for also switching to a new bigger malloc_simple heap located in the new stack.
