arm: dts: k3-j721e-sk-u-boot: fix boot on j721e SK

2023-04-03T18:54:16Z

J721e SK has been broken since at least March 2022. The main-navss and mcu-navss nodes were renamed and this caused the A72 SPL to fail early in the boot even before the serial port was enabled. Fix this. A later patch series between v2022.07 and v2022.10 additionally broke boot on this board by introducing hbmc nodes which are not present on this board. The right fix is to disable these by default in the SOC dtsi file, but for now we can also disable them in the u-boot dtsi. With both these fixed, we can now boot the j721e SK board fully from mainline u-boot.

pico-imx6: Pass the mmc alias to fix boot regression

2023-04-03T14:14:34Z

Originally, the mmc aliases node was present in imx6qdl-pico.dtsi. After the sync with Linux in commit d0399a46e7cd ("imx6dl/imx6qdl: synchronise device trees with linux"), the aliases node is gone as the upstream version does not have it. This causes a boot regression in which the eMMC card cannot be found anymore. Fix it by passing the alias node in the u-boot.dtsi file to restore the original behaviour where the eMMC (esdhc3) was mapped to mmc0.

imx6sx-udoo-neo-basic: Introduce the u-boot.dtsi

2023-03-28T14:58:16Z

After the conversion to DM_SERIAL in commit 01f372d8d62b ("udoo_neo: Select DM_SERIAL and drop iomux board level init") the SPL log is gone and the U-Boot proper log becomes incomplete: Core: 80 devices, 18 uclasses, devicetree: separate MMC: FSL_SDHC: 1, FSL_SDHC: 2 Loading Environment from MMC... OK In: serial@2020000 Out: serial@2020000 Err: serial@2020000 Net: eth0: ethernet@2188000 Hit any key to stop autoboot: 0 Introduce the u-boot.dtsi file that passes the u-boot,dm-pre-reloc properties to the relevant nodes so that UART can be used early in SPL. With this change, the complete SPL and U-Boot messages are seen again. Signed-off-by: Fabio Estevam

rockchip: Use BOOTSTD_DEFAULTS if not DISTRO_DEFAULTS

2023-03-27T15:16:04Z

When we do not enable DISTRO_DEFAULTS (generally, to get distro_bootcmd) we instea do want to imply BOOTSTD_DEFAULTS so that when using bootstd the general distro boot functionality will still work. Signed-off-by: Tom Rini

rockchip: Disable DISTRO_DEFAULTS for rk3399 boards

These board have moved to standard boot but the old 'distro_bootcmd' command is still active. Disable DISTRO_DEFAULTS to fix this. Signed-off-by: Simon Glass Tested-by: Vagrant Cascadian

mmc: bcm2835-host: let firmware manage the clock divisor

2023-03-24T14:43:20Z

Newer firmware can manage the SDCDIV clock divisor register, allowing the divisor to scale with the core as necessary. Leverage this ability if the firmware supports it. Adapted from the following raspberrypi Linux kernel commit: bcm2835-sdhost: Firmware manages the clock divisor https://github.com/raspberrypi/linux/commit/08532d242d7702ae0add95096aa49c5e96e066e2 Signed-off-by: Vincent Fazio Signed-off-by: Peter Robinson

arm: rpi: fallback to max clock rate for MMC clock

2023-03-24T14:43:20Z

In rpi-firmware 25e2b597ebfb2495eab4816a276758dcc6ea21f1, the GET_CLOCK_RATE mailbox property was changed to return the last value set by SET_CLOCK_RATE. https://github.com/raspberrypi/firmware/issues/1619#issuecomment-917025502 Due to this change in firmware behavior, bcm2835_get_mmc_clock now returns a clock rate of zero since we do not issue SET_CLOCK_RATE. This results in degraded MMC performance. SET_CLOCK_RATE fixes the clock to a specific value and disables scaling so is not an ideal solution. Instead, fallback to GET_MAX_CLOCK_RATE in bcm2835_get_mmc_clock if GET_CLOCK_RATE returns zero. Signed-off-by: Vincent Fazio Signed-off-by: Peter Robinson

arm: mach-k3: am62: move scratch board area to HSM RAM

2023-03-22T16:51:09Z

On high security devices, ROM enables firewalls to protect the OCSRAM region access during bootup. Only after TIFS has started (and had time to disable the OCSRAM firewall region) will we have write access to the region. So, move scratch board area to HSM RAM. Signed-off-by: Kamlesh Gurudasani

console: Use flush() before panic and reset

2023-03-22T16:51:08Z

To make sure the panic and the reset messages will go out, console flush() should be used. Sleep periods do not work in early u-boot phase when timer driver is not initialized yet.
