In U-Boot proper this is the oscillator device, not the SoC clock device. As a result the HDMI display does not work. Fix this by calling rockchip_get_clk() instead.

* | spl: Lightweight UBI and UBI fastmap supportThomas Gleixner2016-07-22-0/+1170
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Booting a payload out of NAND FLASH from the SPL is a crux today, as it requires hard partioned FLASH. Not a brilliant idea with the reliability of todays NAND FLASH chips. The upstream UBI + UBI fastmap implementation which is about to brought to u-boot is too heavy weight for SPLs as it provides way more functionality than needed for a SPL and does not even fit into the restricted SPL areas which are loaded from the SoC boot ROM. So this provides a fast and lightweight implementation of UBI scanning and UBI fastmap attach. The scan and logical to physical block mapping code is developed from scratch, while the fastmap implementation is lifted from the linux kernel source and stripped down to fit the SPL needs. The text foot print on the board which I used for development is: 6854 0 0 6854 1abd drivers/mtd/ubispl/built-in.o Attaching a NAND chip with 4096 physical eraseblocks (4 blocks are reserved for the SPL) takes: In full scan mode: 1172ms In fastmap mode: 95ms The code requires quite some storage. The largest and unknown part of it is the number of fastmap blocks to read. Therefor the data structure is not put into the BSS. The code requires a pointer to free memory handed in which is initialized by the UBI attach code itself. See doc/README.ubispl for further information on how to use it. This shares the ubi-media.h and crc32 implementation of drivers/mtd/ubi There is no way to share the fastmap code, as UBISPL only utilizes the slightly modified functions ubi_attach_fastmap() and ubi_scan_fastmap() from the original kernel ubi fastmap implementation.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | flash_full_status_check() checks bit XSR.7 on Intel chips. This should be done by only checking bit 7 and not by comparing the whole status byte or word with 0x80. This fixes the non-working block erase in the pflash emulation of Qemu when used with the MIPS Malta board. MIPS Malta uses x32 mode to access the pflash device. In x32 mode Qemu mirrors the lower 16 bits of the status word into the upper 16 bits. Thus the CFI driver gets a status word of 0x8080 in x32 mode. If flash_full_status_check() uses flash_isequal(), then it polls for XSR.7 by comparing 0x8080 with 0x80 which never becomes true.

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PERIPH_ID_SDMMC4(131) is not continous value with PERIPH_ID_SDMMC0(75). If there is no 'index' property in fdt, then dev_index should be assigned to dev_id(Peripheral ID). At this time, dev_index should be "56". It means Exynos SoC has "56" numbers of DWMMC IP. To prevent this behavior, it needs to check the maximum device index.
