* sunxi: Support booting from SPI flashSiarhei Siamashka2016-07-15-0/+296
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The S25FS-S family physical sectors may be configured as a hybrid combination of eight 4-kB parameter sectors at the top or bottom of the address space with all but one of the remaining sectors being uniform size. The default status of the flash is in this hybrid architecture. The parameter sectors and the uniform sectors have different erase commands.

* sf: fix timebase data type in _wait_ready()Stephen Warren2016-04-25-1/+2
| | | | | | | | | | | | | | get_timer() returns an unsigned 64-bit value, but is currently assigned to a signed 32-bit variable. Due to sign extension and data truncation, this causes the timeout loop in spi_flash_cmd_wait_ready() to immediately (and incorrectly) fire for about 50% of all time values, based on whether bit 31 is set. In sandbox at least, this causes the test to pass or fail based on system uptime, as opposed to time since the U-Boot binary was started.

* sf: Correct data types in stm_is_locked_sr()Marek Vasut2016-03-12-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | The stm_is_locked_sr() function is picked from Linux kernel. For reason unknown, the 64bit data types used by the function and present in Linux were replaced with 32bit unsigned ones, which causes trouble. The testcase performed was done using ST M25P80 chip. The command used was: => sf protect unlock 0 0x10000 The call chain starts in stm_unlock(), which calls stm_is_locked_sr() with negative ofs argument. This works fine in Linux, where the "ofs" is loff_t, which is signed long long, while this fails in U-Boot, where "ofs" is u32 (unsigned int). Because of this signedness problem, the expression past the return statement to be incorrectly evaluated to 1, which in turn propagates back to stm_unlock() and results in -EINVAL. The correction is very simple, just use the correctly sized data types with correct signedness in the function to make it work as intended.
