2021-07-16stm32mp: use device sequence number in boot_instance variablePatrick Delaunay3-9/+46
Use the device sequence number in boot_instance variable and no more the SDMMC instance provided by ROM code/TF-A. After this patch we don't need to define the mmc alias in device tree, for example: mmc0 = &sdmmc1; mmc1 = &sdmmc2; mmc2 = &sdmmc3; to have a correct mapping between the ROM code boot device = "${boot_device}${boot_instance}" and the MMC device in U-Boot. With this patch the 'mmc0' device (used in mmc commands) is always used when only one instance sdmmc is activated in device tree, even if it is only the sdmmc2 or sdmmc3.

2021-07-16image: android: Automatically detect more compression typesStephan Gerhold1-1/+1
At the moment android_image_get_kcomp() can automatically detect LZ4 compressed kernels and the compression specified in uImages. However, especially on ARM64 Linux is often compressed with GZIP. Attempting to boot an Android image with a GZIP compressed kernel image currently results in a very strange crash, e.g. Starting kernel ... "Synchronous Abort" handler, esr 0x02000000 ... Code: 5555d555 55555d55 555f5555 5d555d55 (00088b1f) Note the 1f8b, which are the "magic" bytes for GZIP images. U-Boot already has the image_decomp_type() function that checks for the magic bytes of bzip2, gzip, lzma and lzo. It's easy to make use of it here to increase the chance that we do the right thing and the user does not become confused with strange crashes. This allows booting Android boot images that contain GZIP-compressed kernel images. Signed-off-by: Stephan Gerhold <stephan@gerhold.net>
2021-07-16fit: Load DTO into temporary buffer and ignore load addressMarek Vasut1-4/+28
The current fitImage DTO implementation expects each fitImage image subnode containing DTO to have 'load' property, pointing somewhere into memory where the DTO will be loaded. The address in the 'load' property must be different then the base DT load address and there must be sufficient amount of space between those two addresses. Selecting and using such hard-coded addresses is fragile, error prone and difficult to port even across devices with the same SoC and different DRAM sizes. The DTO cannot be applied in-place because fdt_overlay_apply_verbose() modifies the DTO when applying it onto the base DT, so if the DTO was used in place within the fitImage, call to fdt_overlay_apply_verbose() would corrupt the fitImage. Instead of copying the DTO to a specific hard-coded load address, allocate a buffer, copy the DTO into that buffer, apply the DTO onto the base DT, and free the buffer. The upside of this approach is that it is no longer necessary to select and hard-code specific DTO load address into the DTO. The slight downside is the new malloc()/free() overhead for each DTO, but that is negligible (*).

2021-07-16lib/vsprintf.c: remove unused ip6_addr_string()Rasmus Villemoes1-1/+5
There's currently no user of %p[iI]6, so including ip6_addr_string() in the image is a waste of bytes. It's easy enough to have the compiler elide it without removing the code completely. The closest I can find to anybody "handling" ipv6 in U-Boot currently is in efi_net.c which does if (ipv6) { ret = EFI_UNSUPPORTED; As indicated in the comment, it can easily be put back, but preferably under a config knob.
