2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>

2017-10-25SPL: SPI: select SPL_SPI_FLASH_SUPPORT on SPL_SPI_SUNXIAndre Przywara
The Allwinner SPI flash SPL boot support is guarded by the SPL_SPI_SUNXI symbol. But despite its generic name, the actual only use case for this is to provide SPI flash support to the SPL, which requires CONFIG_SPL_SPI_FLASH_SUPPORT to be defined. Select this symbol from the SPL_SPI_SUNXI Kconfig definition. This avoids doing this explicitly in the defconfig, and fixes SPI booting on the Pine64 SoPine (and -LTS version) and the OrangePi Win board (both with SPI flash).

2017-09-27sf: bar: Clean BA24 Bank Address Register bit after read/write/erase operationLukasz Majewski
The content of Bank Address Register (BAR) is volatile. It is cleared after power cycle or reset command (RESET F0h). Some memories (like e.g. s25fl256s) use it to access memory larger than 0x1000000 (16 MiB). The problem shows up when one: 1. Reads/writes/erases memory > 16 MiB 2. Calls "reset" u-boot command (which is not causing BAR to be cleared) In the above scenario, the SoC ROM sends 0x000000 address to read SPL. Unfortunately, the BA24 bit is still set and hence it receives content from 0x1000000 (16 MiB) memory address. As a result the SoC aborts and we hang. Only power cycle can take the SoC out of this state. How to reproduce/test: sf probe; sf erase 0x1200000 0x800000; reset sf probe; sf erase 0x1200000 0x800000; sf write 0x11000000 0x1200000 0x800000; reset sf probe; sf read 0x11000000 0x1200000 0x800000; reset Signed-off-by: Lukasz Majewski <lukma@denx.de> [Fixed comment text on clean_bar function] Signed-off-by: Jagan Teki <jagan@openedev.com> Reviewed-by: Jagan Teki <jagan@openedev.com>

2016-12-15Revert "sf: Fix quad bit set for micron devices"Cyrille Pitchen
This reverts commit c56ae7519f141523ba1248b22b5b5169b21772fe. Once the 'Quad Enable' bit is cleared in their Enhanced Volatile Configuration Register (EVCR), Micron memories expect ALL commands to use the SPI 4-4-4 protocol. Commands using SPI 1-y-z protocols are no longer accepted. Within the reverted commit, the write_evcr() function is implemented using the spi_flash_write_common(), which is a shortcut for the [ spi_flash_cmd_write_enable(), spi_flash_cmd_write(), spi_flash_cmd_wait_ready() ] sequence. Since the internal state of the Micron memory has been changed when the spi_flash_cmd_write() function completes, the later call of the spi_flash_cmd_wait_ready() function fails. Indeed the SPI controller driver is not aware of the SPI protocol switch. Further patches will fix the support of Micron QSPI memories.
