SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12Z

When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini

Move most CONFIG_HAVE_BLOCK_DEVICE to Kconfig

2018-02-09T00:09:03Z

config_fallbacks.h has some logic that sets HAVE_BLOCK_DEVICE based on a list of enabled options. Moving HAVE_BLOCK_DEVICE to Kconfig allows us to drastically shrink the logic in config_fallbacks.h Signed-off-by: Adam Ford [trini: Rename HAVE_BLOCK_DEVICE to CONFIG_BLOCK_DEVICE] Signed-off-by: Tom Rini

iso: Reduce verbosity on test and info calls

2017-10-16T13:42:51Z

The test and info callbacks into the partition callback struct are used by the "part list" command on the command line. That command is used by the distro script. With verb=1 set, "part list" thus throws a lot of warnings about partitions it can't find when an upper layer searches for partitions. So let's reduce verbosity to bring it to the same level of noise as the other partition targets. Signed-off-by: Alexander Graf

disk: part: align buffer so it can be used with DMA enabled drivers

2017-08-26T18:56:15Z

When using ISO partitions with a DMA enabled block device driver reading the ISO partition leads to unaligned DMA operations: CACHE: Misaligned operation at range [bffb7da8, bffb85a8] Align the buffer to make sure we pass a buffer which works for DMA operations.

disk: part: refactor generic name creation for DOS and ISO

2016-10-02T00:04:56Z

In both DOS and ISO partition tables the same code to create partition name like "hda1" was repeated. Code moved to into a new function part_set_generic_name() in part.c and optimized. Added recognition of MMC and SD types, name is like "mmcsda1". Signed-off-by: Petr Kulhavy Reviewed-by: Tom Rini Acked-by: Steve Rae Reviewed-by: Simon Glass

disk: part: implement generic function part_get_info_by_name()

2016-10-02T00:04:45Z

So far partition search by name has been supported only on the EFI partition table. This patch extends the search to all partition tables. Rename part_get_info_efi_by_name() to part_get_info_by_name(), move it from part_efi.c into part.c and make it a generic function which traverses all part drivers and searches all partitions (in the order given by the linked list). For this a new variable struct part_driver.max_entries is added, which limits the number of partitions searched. For EFI this was GPT_ENTRY_NUMBERS. Similarly the limit is defined for DOS, ISO, MAC and AMIGA partition tables. Signed-off-by: Petr Kulhavy Reviewed-by: Tom Rini Acked-by: Steve Rae

iso: Fix part info command

2016-07-22T18:46:19Z

Partitions on the iso el torito partition table interpreter only start from partition 1. So when printing out the tables, let's also start counting at 1. Signed-off-by: Alexander Graf

iso: Allow 512 byte sector size

2016-04-18T21:11:35Z

Real CD-ROMs are pretty obsolete these days. Usually people still keep iso files around, but just put them on USB sticks or SD cards and expect them to "just work". To support this use case with El Torito images, add support for 512 byte sector size to the iso parsing code. Signed-off-by: Alexander Graf

iso: Start with partition 1

2016-04-18T21:11:34Z

The generic partition code treats partition 0 as "whole disk". So we should start with partition 1 as the first partition in the iso partition table. Signed-off-by: Alexander Graf

iso: Make little endian and 64bit safe

The iso partition table implementation has a few endian and 64bit problems. Clean it up a bit to become endian and bitness safe. Signed-off-by: Alexander Graf
