| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By default, the subordinate is set equally to the secondary bus (1) when the RC boots, and does not alter afterwards. This means that theoretically, the highest bus reachable downstream is bus 1. Force the PCIe RC subordinate to 0xff, otherwise no downstream devices will be detected behind bus 1 if the booting OS does not allow enumerating a higher busnr than the subordinate value of the primary bus.

| * | spi: fsl_qspi: support i.MX6UL/6ULLL/7DPeng Fan2018-01-121-2/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The QSPI module on i.MX7D is modified from i.MX6SX. The module used on i.MX6UL/6ULL is reused from i.MX7D. They share same tx buffer size. The endianness is not set at qspi driver initialization. So if we don't boot from QSPI, we will get wrong endianness when accessing from AHB address directly. Add the compatible entry for 6ul/7d. Signed-off-by: Peng Fan <peng.fan@nxp.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On i.MX7ULP, the fuse words (except bank 0 and 1) only supports to write once, because they use ECC mode. Multiple writes may damage the ECC value and cause a wrong fuse value decoded when reading. This patch adds a checking before the fuse word programming, only can write when the word value is 0.

| * mmc: fsl_esdhc: Fix eMMC 1.8v setting issuePeng Fan2018-01-131-4/+5
| | | | | | | | | | | | | | | | | | | | | | | | Current USDHC driver will reset VSELECT to 0 (3.3v) during mmc init, then set to 1 for 1.8v eMMC I/O. When booting from eMMC, since ROM has already set VSELECT to 1.8v before running the u-boot. This reset in USDHC driver causes a short 2.2v pulse on CMD pin. Fix this issue by not reset VSELECT to 0 when 1.8v flag is set. Signed-off-by: Ye Li <ye.li@nxp.com> Signed-off-by: Peng Fan <peng.fan@nxp.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With certain SD cards like Kingston 8GB/16GB UHS card, it is seen that MMC_CMD_ALL_SEND_CID cmd fails on first attempt, but succeeds subsequently. Therefore, retry MMC_CMD_ALL_SEND_CID cmd a few time as done in Linux kernel. Similarly, it is seen that MMC_CMD_SET_BLOCKLEN may fail on first attempt, therefore retry this cmd a few times as done in kernel.
