2026-01-28board: nxp: Rename board directory from board/freescale to board/nxpAlice Guo
This patch renames the board directory from board/freescale to board/nxp because NXP now provides Board Support Packages (BSPs) and tools for the former Freescale i.MX and other i.MX products. All relevant references have been updated accordingly. This change does not affect functionality. Signed-off-by: Alice Guo <[email protected]> Reviewed-by: Fabio Estevam <[email protected]>
2025-06-20env: Rename SYS_MMC_ENV_DEV to ENV_MMC_DEVICE_INDEXMarek Vasut
Rename the variable and add ENV_ prefix, so that all configuration options which are related to environment would have an CONFIG_ENV_ prefix. No functional change. Use ENV_MMC_DEVICE_INDEX to clarify this is the SD/MMC device index, a number, as enumerated by U-Boot. Update the help text accordingly. Signed-off-by: Marek Vasut <[email protected]>
2024-11-09imx: hab: Make imx_hab_is_enabled dependent on FIELD_RETURNPaul Geurts
The decision on whether HAB is enabled is solely based on the SEC_CONFIG fuse. The HAB FIELD_RETURN feature is able to permanently disable HAB on a CPU, after which it is able to boot unsigned firmware. U-Boot however does not take into account the FIELD_RETURN mode, and refuses to boot unsigned software when the feature is enabled. Also take the FIELD_RETURN fuse into account when deciding whether HAB is enabled. When The FIELD_RETURN fuse is blown, HAB is not enabled. Tested on i.MX8M Mini, i.MX8M Plus, i.MX8M Nano and i.MX6ULL Signed-off-by: Paul Geurts <[email protected]>

2022-02-05imx: Enable ACTLR.SMP in SPL for i.MX6/7Sven Schwermer
Similar to what has been done before with c5437e5b for u-boot proper, we enable the SMP bit for SPL as well. This is necessary when SDP booting straight into Linux, i.e. falcon boot. When SDP boot mode is active, the ROM code does not set this bit which makes the caches not work once activated in Linux. On an i.MX6ULL (528MHz), this reduces a minimal kernel's boot time into an initramfs shell from ~6.1s down to ~1.2s.

2021-10-07mx7ulp: Update wdog disable sequenceYe Li
Update the mx7ulp wdog disable sequence to avoid potential reset issue in unlock or refresh sequence. Both sequence need two words write to wdog CNT register in 16 bus clocks window, if miss the window, the write will cause violation in wdog and reset the chip. Current u-boot code is using writel() function which has a DMB barrier to order the memory access. The DMB between two words write may introduce some delay in certain circumstance, causing the wdog reset due to 16 bus clock window requirement. Also, WDOG1 might have been enabled already depending on FUSE hence we need to be as close as possible to its reconfiguration timing requirement of 128 bus clock limit. This patch replaces writel() function by __raw_writel() to avoid such issue, and improve to check if watchdog is already disabled or unlocked.

2021-03-02reset: Remove addr parameter from reset_cpu()Harald Seiler
Historically, the reset_cpu() function had an `addr` parameter which was meant to pass in an address of the reset vector location, where the CPU should reset to. This feature is no longer used anywhere in U-Boot as all reset_cpu() implementations now ignore the passed value. Generic code has been added which always calls reset_cpu() with `0` which means this feature can no longer be used easily anyway. Over time, many implementations seem to have "misunderstood" the existence of this parameter as a way to customize/parameterize the reset (e.g. COLD vs WARM resets). As this is not properly supported, the code will almost always not do what it is intended to (because all call-sites just call reset_cpu() with 0). To avoid confusion and to clean up the codebase from unused left-overs of the past, remove the `addr` parameter entirely. Code which intends to support different kinds of resets should be rewritten as a sysreset driver instead. This transformation was done with the following coccinelle patch: @@ expression argvalue; @@ - reset_cpu(argvalue) + reset_cpu() @@ identifier argname; type argtype; @@ - reset_cpu(argtype argname) + reset_cpu(void) { ... } Signed-off-by: Harald Seiler <[email protected]> Reviewed-by: Simon Glass <[email protected]>

Move this out of the common header and include it only where needed.

2020-05-18arm: Don't include common.h in header filesSimon Glass
It is bad practice to include common.h in other header files since it can bring in any number of superfluous definitions.
