SPDX: Convert all of our single license tags to Linux Kernel style 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 <trini@konsulko.com>

sandbox: Generalise SPL booting At present sandbox only supports jumping to a file, to get to the next U-Boot phase. We want to support other methods, so update the code to use an enum for the method. Also use the Use board_boot_order() to set the order, so we can add more options. Also add the MMC methods into the BOOT_DEVICE enum so that booting from MMC can be supported. Signed-off-by: Simon Glass <sjg@chromium.org>

BOOT_DEVICE_VBE,
test: spl: Add a test for the NET load method Add a test for loading U-Boot over TFTP. As with other sandbox net routines, we need to initialize our packets manually since things like net_set_ether and net_set_udp_header always use "our" addresses. We use BOOTP instead of DHCP, since DHCP has a tag/length-based format which is harder to parse. Our TFTP implementation doesn't define as many constants as I'd like, so I create some here. Note that the TFTP block size is one-based, but offsets are zero-based. In order to avoid address errors, we need to set up/define some additional address information settings. dram_init_banksize would be a good candidate for settig up bi_dram, but it gets called too late in board_init_r.

BOOT_DEVICE_CPGMAC,
test: spl: Add a test for the NOR load method Add a test for the NOR load method. Since NOR is memory-mapped we can substitute a buffer instead. The only major complication is testing LZMA decompression. It's too complex to implement LZMA compression in a test, and we have no in-tree compressor, so we just include some pre-compressed data. This data was generated through something like generate_data(plain, plain_size, "lzma") cat plain.dat | lzma | hexdump -C and was cleaned up further in my editor.

BOOT_DEVICE_NOR,
test: spl: Add a test for the SPI load method Add test for the SPI load method. This one is pretty straightforward. We can't enable FIT_EXTERNAL with LOAD_FIT_FULL because spl_spi_load_image doesn't know the total image size and has to guess from fdt_totalsize. This doesn't include external data, so loading it will fail. Signed-off-by: Sean Anderson <seanga2@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org>

sandbox: Support executables for more phases The SPL header has a function for obtaining the phase in capital letters, e.g. 'SPL'. Add one for lower-case also, as used by sandbox. Use this to generalise the sandbox logic for determining the filename of the next sandbox executable. This can provide support for VPL. Signed-off-by: Simon Glass <sjg@chromium.org>
