A bootmeth is a method of locating an operating system. For now, just add the uclass itself. Drivers for particular bootmeths are added later. If no bootmeths devices are included in the devicetree, create them automatically. This avoids the need for boilerplate in the devicetree files. Signed-off-by: -
A 'bootdev' is a device which can be used to boot an operating system. It is a child of the media device (e.g. MMC) which handles reading files from that device, such as a bootflow file. Add a uclass for bootdev and the various helpers needed to make it work. Also add a binding file, empty for now. Signed-off-by: -

A bootflow encapsulates the process used to boot an operating system. It typically has a control file (such as extlinux.conf) and information about which 'bootdev' it came from. Add the header file for this first, since it is needed by all other files. Signed-off-by: -

In some cases two devices are related and the only way to tell is to check that the names partially patch. Add a way to check this without needing to create a new string for the comparison. Fix the comment for device_find_child_by_namelen() while we are here. Signed-off-by: -
It seems that namelen is more common in U-Boot. Rename this function to fit in better. Also fix a bug where it breaks the operation of uclass_get_by_name() and add a test. Signed-off-by:

At present it is not possible to find out which part of the string is the number part and which is before it. Add a new variant which provides this feature, so we can separate the two in the caller. Signed-off-by: -
At present this has a minor bug in that it reads the byte before the start of the string, if it is empty. Also it doesn't handle a non-numeric prefix which is only one character long. Fix these bugs with a reworked implementation. Add a test for the second case. The first one is hard to test. Signed-off-by: -
Tweak a few comments to kep sphinx happy, in case we want to include this file one day. Also fix the 'exxamine' typo. Patch-notes: This uses: sed -i 's/@param \(\S*\)\s*/@\1: /' include/vsprintf.h to convert the @param to the new format. Signed-off-by: -

Unless you have a spare Apple Silicon machine, getting access to the serial port on Apple Silicon machines requires special hardware. Given that most machines come with a built-in screen the framebuffer is likely to be the most convenient output device for most users. While U-Boot will output to both serial and framebuffer, OSes might not. Therefore set stdout-path to point at /chosen/framebuffer when a keyboard is connected to the machine. This behaviour can be overridden by setting the "stdout" variable in the U-Boot environment. I addition to that keep the serial console as the default when running under the m1n1 hypervisor. The m1n1 hypervisor virtualizes the serial port such that it can be easily accessed from any other machine with a USB port. Signed-off-by:

- U-boot's PXE flow supports prefixing your bootfile name with an IP address to fetch from a server other than the DHCP server, e.g. `hostIPaddr:bootfilename`: https://github.com/u-boot/u-boot/commit/a93907c43f847f076dd0e34ee3b69b5e8e6d0d29 - However, this breaks bootfile paths which contain a colon, e.g. `f0:ad:4e:10:1b:87/7/pxelinux.cfg/default` - This patch checks whether the `hostIPaddr` prefix is a valid IP address before overriding the serverIP otherwise the whole bootfile path is preserved Signed-off-by:

distro_bootcmd uses this construct a few times to test $fdt_addr_r, and fall back on $fdtcontroladdr if not set/invalid: if fdt addr ${fdt_addr_r}; then ... else ... fi If the `fdt addr` test fails, it prints the following message on the console, suggesting there is an error when there is not: libfdt fdt_check_header(): FDT_ERR_BADMAGIC To remove this potentially confusing error message, this patch adds -q as a 'quiet' option for fdt addr, and uses this flag in config_distro_bootcmd.h Signed-off-by:Peter Hoyes <Peter.Hoyes@arm.com>

Commit 690af718 changed this condition from an explicit IS_ENABLED(CONFIG_SPL_SEPARATE_BSS) to CONFIG_IS_ENABLED(SEPARATE_BSS) The documentation for CONFIG_IS_ENABLED() in include/linux/kconfig.h implies that we will get the correct behaviour, but the actual behaviour differs such that this condition is now always false. This stopped TPL being able to load the device tree blob at least on the ROCKPro64 board (RK3399 SoC), since the wrong device tree location was chosen. The issues causing this behaviour with CONFIG_IS_ENABLED() are: 1. The documentation implies that CONFIG_SPL_BUILD => CONFIG_SPL_<option> is considered before the TPL equivalent. Actually, the TPL options have higher priority - see definition of _CONFIG_PREFIX. 2. The documentation implies a fallthrough, eg. if CONFIG_SPL_BUILD is defined but the CONFIG_SPL_<option> is not, then it will proceed to check if CONFIG_TPL_BUILD Actually, if CONFIG_TPL_BUILD is defined, then it stops there and CONFIG_SPL_BUILD is not considered - see definition of _CONFIG_PREFIX. During TPL build, at least for the ROCKPro64, both CONFIG_TPL_BUILD and CONFIG_SPL_BUILD are defined, but because of the above, only TPL options are considered. Since there is no CONFIG_TPL_SEPARATE_BSS, this fails. Fixes: 690af718 ("fdt: Correct condition for SEPARATE_BSS") Signed-off-by:

Currently the space between kernel_addr_r and the fdt_addr_r is only 32MB. To have enough space to load kernel images bigger than 32MB change the variables to a feasible value. The new environment variables layout is based on the scheme from "include/configs/ti_armv7_common.h". The CONFIG_SYS_LOAD_ADDR value is set to 0x42000000. With that we have the same value as for the kernel_addr_r. Signed-off-by:
