imx: Fix imx8m FIT script issue

2020-04-09T17:07:32Z

The FIT config node has reversed ATF and u-boot: ATF is set to 'firmware' but u-boot is set to 'loadables'. This script can work previously because spl fit driver wrongly appends fdt to all loadable images. With the issue fixed in commit 9d15d1d1c24f ("Revert "common: spl_fit: Default to IH_OS_U_BOOT if FIT_IMAGE_TINY enabled"") the u-boot in 'loadables' does not have fdt appended and fails to work. So correct the script by moving u-boot to 'firmware' and ATF to 'loadables'. Signed-off-by: Ye Li Reported-by: Matt Porter Tested-by: Matt Porter

ARM: dts: imx8qxp-colibri: dm-pre-proper for pd_dma nodes

2020-04-07T08:41:10Z

pd_dma_* nodes should be accessible during pre-relocation stage of U-Boot proper for properly handling power domains. This fixes the issue with permanent failing of invocation of power_domain_get_by_index() in the common code of DM power domain uclass (drivers/power/domain/power-domain-uclass.c).

ARM: dts: imx8qxp-colibri: replace dm-spl with dm-pre-proper

2020-04-07T08:41:02Z

For non-SPL/TPL setups dm-spl, dm-tpl, dm-pre-proper, dm-pre-reloc are handled equally, forcing the nodes with these properties to be accessible and device being probed before pre-relocation of U-Boot proper (drivers/core/util.c): bool ofnode_pre_reloc(ofnode node) { /* for SPL and TPL the remaining nodes after the fdtgrep 1st pass * had property dm-pre-reloc or u-boot,dm-spl/tpl. * They are removed in final dtb (fdtgrep 2nd pass) */ return true; if (ofnode_read_bool(node, "u-boot,dm-pre-reloc")) return true; if (ofnode_read_bool(node, "u-boot,dm-pre-proper")) return true; /* * In regular builds individual spl and tpl handling both * count as handled pre-relocation for later second init. */ if (ofnode_read_bool(node, "u-boot,dm-spl") || ofnode_read_bool(node, "u-boot,dm-tpl")) return true; return false; } Howewer, to avoid confusion in future, replace dm-spl `%s/dm-spl/dm-pre-proper/g` properties to dm-pre-proper to explicitly state that they are handled during pre-relocation stage of U-Boot proper.

ARM: dts: stm32: Temporarily drop cd-gpios from AV96 DT

2020-04-05T23:07:13Z

The card-detect GPIO and any other GPIO access currently doesn't work in U-Boot SPL on any STM32 platform and crashes the SPL. To work around this problem on AV96 right before release, remove the cd-gpios from DT. This patch must be reverted right after release, once the proper fix for the GPIO driver, "gpio: stm32: support gpio ops in SPL", is applied.

mach-snapdragon: Fix overwriting last digit of serial number

When generating the MAC address based on the boards serial number the last digit was overwritten with the null termination. That way boards with serial numbers close to each other would use the same MAC address. Signed-off-by: Jan-Christoph Tebbe

ARM: tegra: Add NVIDIA Jetson Nano Developer Kit support

2020-04-02T21:30:02Z

The Jetson Nano Developer Kit is a Tegra X1-based development board. It is similar to Jetson TX1 but it is not pin compatible. It features 4GB of LPDDR4, a SPI NOR flash for early boot firmware and an SD card slot used for storage. HDMI 2.0 or DP 1.2 are available for display, four USB ports (3 USB 2.0 and 1 USB 3.0) can be used to attach a variety of peripherals and a PCI Ethernet controller provides onboard network connectivity. NVMe support has also been added. Env save is at the end of QSPI (4MB-8K). A 40-pin header on the board can be used to extend the capabilities and exposed interfaces of the Jetson Nano.

mmc: t210: Fix 'bad' SD-card clock when doing 400KHz card detect

2020-04-02T21:30:01Z

According to the HW team, for some reason the normal clock select code picks what appears to be a perfectly valid 375KHz SD card clock, based on the CAR clock source and SDMMC1 controller register settings (CAR = 408MHz PLLP0 divided by 68 for 6MHz, then a SD Clock Control register divisor of 16 = 375KHz). But the resulting SD card clock, as measured by the HW team, is 700KHz, which is out-of-spec. So the WAR is to use the values given in the TRM PLLP table to generate a 400KHz SD-clock (CAR clock of 24.7MHz, SD Clock Control divisor of 62) only for SDMMC1 on T210 when the requested clock is <= 400KHz. Note that as far as I can tell, the other requests for clocks in the Tegra MMC driver result in valid SD clocks. Signed-off-by: Tom Warren Reviewed-by: Jaehoon Chung
