2021-07-10mx6sabresd: Make checkboard respect CONFIG_NXP_BOARD_REVISIONCody Gray1-1/+4
The default implementation of checkboard() calls the nxp_board_rev_string() function to retrieve a character representing the revision number of the board. However, this attempt to retrieve the revision number may fail in certain situations or be otherwise undesirable. There is already a configuration option to avoid retrieving the revision number of the board: CONFIG_NXP_BOARD_REVISION. In fact, if this option is enabled, the nxp_board_rev_string() function's definition will be omitted entirely, meaning that the previous implementation of checkboard() would result in a linker error. This changeset makes the default implementation of checkboard() respect the CONFIG_NXP_BOARD_REVISION configuration option, only attempting to retrieve the board revision number if that option is defined.

2021-07-10ARM: imx: Pick correct eMMC boot partition from ROM logMarek Vasut1-0/+61
In case the iMX8M boot from eMMC boot partition and the primary image is corrupted, the BootROM is capable of starting a secondary image in the other eMMC boot partition as a fallback. However, the BootROM leaves the eMMC BOOT_PARTITION_ENABLE setting as it was, i.e. pointing to the boot partition containing the corrupted image, and the BootROM does not provide any indication that this sort of fallback occured. According to AN12853 i.MX ROMs Log Events, Rev. 0, May 2020, it is possible to determine whether fallback event occurred by parsing the ROM event log. In case ROM event ID 0x51 is present, fallback event did occur. This patch implements ROM event log parsing and search for event ID 0x51 for all iMX8M SoCs, and based on that corrects the eMMC boot partition selection. This way, the SPL loads the remaining boot components from the same eMMC boot partition from which it was started, even in case of the fallback.

The Microchip KSZ9477/KSZ9897/KSZ9567 7-Port Gigabit Ethernet Switches support SGMII/RGMII/MII/RMII with register access via SPI, I2C, or MDIO. This driver currently supports I2C register access but SPI or MDIO register access can be easily added at a later time. Tagging is not implemented and instead the active port is tracked to avoid needing a tag to store port information.

2021-07-10net: fec: use device sequence vs index when fetching fecTim Harvey1-1/+1
When using uclass_get_device* to get the FEC device we need to use device sequence instead of index into UCLASS_ETH. In systems where for example a I2C based DSA switch exists it will probe before the FEC master and its ports will be registered first and have the first indexes yet the FEC's sequence comes from the device-tree alias. Take for example the imx8mm-venice-gw7901 board which has an i2c based DSA switch: u-boot=> net list eth1 : lan1 00:0d:8d:aa:00:2f eth2 : lan2 00:0d:8d:aa:00:30 eth3 : lan3 00:0d:8d:aa:00:31 eth4 : lan4 00:0d:8d:aa:00:32 eth0 : ethernet@30be0000 00:0d:8d:aa:00:2e active Thus in this case uclass_get_device(UCLASS_ETH, 0, &dev) returns lan1 which is wrong but uclass_get_device_seq(UCLASS_ETH, 0, &dev) returns ethernet@30be000 which is correct.

2021-07-10Merge branch 'master' of https://source.denx.de/u-boot/custodians/u-boot-sunxiTom Rini42-136/+737
Aside from the usual fixes and updates one visible change is the MMC update, which fixes some lingering bugs and gives a decent speed increase on some boards (9->19 MB/s on H6, 21->43 MB/s on A64 eMMC). I am keeping an watchful eye on bug reports here, to spot any correctness regressions. Another change is finally the enablement of the first USB host port on many boards without micro-USB (data) sockets, like the Pine64 family. That doubles the number of usable USB ports from 1 to 2 on those boards. Some smaller fixes, 4GB DRAM support (on the H616) and a new board (ZeroPi) conclude this first round of changes. Compile-tested for all 157 sunxi boards, boot-tested on Pine H64, Pine64-LTS, OrangePi Zero 2 and BananaPi M2 Berry. Summary: - DT update for H3/H5/H6 - Enable first USB port on boards without micro-USB - ZeroPi board support - 4GB DRAM support for H616 boards - MMC fixes and speed improvement - some fixes

2021-07-10mmc: sunxi: Increase MMIO FIFO read performanceAndre Przywara2-8/+32
To avoid the complexity of DMA operations (with chained descriptors), we use repeated MMIO reads and writes to the SD_FIFO_REG, which allows us to drain or fill the MMC data buffer FIFO very easily. However those MMIO accesses are somewhat costly, so this limits our MMC performance, to between 17 and 22 MB/s, but down to 9.5 MB/s on the H6 (partly due to the lower AHB1 frequency). As it turns out we read the FIFO status register after *every* word we read or write, which effectively doubles the number of MMIO accesses, thus effectively more than halving our performance. To avoid this overhead, we can make use of the FIFO level bits, which are in the very same FIFO status registers. So for a read request, we now can collect as many words as the FIFO level originally indicated, and only then need to update the status register. We don't know for sure the size of the FIFO (and it seems to differ across SoCs anyway), so writing is more fragile, which is why we still use the old method for that. If we find a minimum FIFO size available on all SoCs, we could use that, in a later optimisation. This patch increases the eMMC read speed on a Pine64-LTS from about 22MB/s to 44 MB/s. SD card reads don't gain that much, but with 23 MB/s we now reach the practical limit for 3.3V SD cards. On the H6 we double our transfer speed, from 9.5 MB/s to 19.7 MB/s.
