Several boards enable SPL_FS_FAT and SPL_LIBDISK_SUPPORT when they can't be used (as there is no block device support enabled). Disable these configs. The list of boards was generated with the following command:

$ tools/qconfig.py -f SPL SPL_FS_FAT ~SPL_MMC ~SPL_BLK_FS ~SPL_SATA \ ~SPL_USB_STORAGE ~ENV_IS_IN_FAT ~EFI

LIBDISK was left enabled for the am* boards, since it seems to result in actual size reduction, indicating that partitions are being used for something.

Changes in v7: - Disable FS_FAT for the zynq(mp) boards as well, as suggested by Michal

On real hardware, semihosting calls tend to have a large constant overhead (on the order of tens of milliseconds). Reduce the number of calls by one by reusing the existing fd in smh_fit_read, and closing it at the end of spl_smh_load_image.

dev and priv serve the same purpose, and are never set at the same time. Remove dev and convert all users to priv. While we're at it, reorder bl_len to be last for better alignment.

Simplify things a bit for callers of spl_load_info->read by refactoring it to use units of bytes instead of bl_len. This generally simplifies the logic, as MMC is the only loader which actually works in sectors. It will also allow further refactoring to remove the special-case handling of filename. spl_load_legacy_img already works in units of bytes (oops) so it doesn't need to be changed.

Instead of relying on the presence of filename to determine whether we are dealing with a FAT filesystem (and should DMA-align the buffer), have FAT set bl_len to ARCH_DMA_MINALIGN instead. With this done, we can remove the special-case logic checking for the presence of filename.

Because filesystems are not block-based, we may read less than the size passed to spl_load_info.read. This can happen if the file size is not DMA-aligned. This is fine as long as we read the amount we originally wanted to. Modify the conditions for callers of spl_load_info.read to check against the original, unaligned size to avoid failing spuriously.

For filesystems, filename serves the same purpose as priv. However, spl_load_fit_image also uses it to determine whether to use a DMA-aligned buffer. This is beneficial for FAT, which uses a bounce-buffer if the destination is not DMA-aligned. However, this is unnecessary now that filesystems set bl_len to ARCH_DMA_MINALIGN instead. With this done, we can remove filename entirely.

Aligning addresses and sizes causes overhead which is unnecessary when we are not loading from block devices. Remove bl_len when it is not needed.

For example, on iot2050 we save 144 bytes with this patch (once the rest of this series is applied):

We use panic() instead of BUILD_BUG_ON in spl_set_bl_len because we still need to be able to compile it for things like mmc_load_image_raw_sector, even if that function will not be used.

Implementers of SPL_LOAD_IMAGE_METHOD have to correctly determine what type of image is being loaded and then call the appropriate image load function correctly. This is tricky, because some image load functions expect the whole image to already be loaded (CONFIG_SPL_LOAD_FIT_FULL), some will load the image automatically using spl_load_info.read() (CONFIG_SPL_LOAD_FIT/CONFIG_SPL_LOAD_IMX_CONTAINER), and some just parse the header and expect the caller to do the actual loading afterwards (legacy/raw images). Load methods often only support a subset of the above methods, meaning that not all image types can be used with all load methods. Further, the code to invoke these functions is duplicated between different load functions.

To address this problem, this commit introduces a "spl_load" function. It aims to handle image detection and correct invocation of each of the parse/load functions.

Although this function generally results in a size reduction with several users, it tends to bloat boards with only a single user. This is generally because programmers open-coding the contents of this function can make optimizations based on the specific loader. For example, NOR flash is memory-mapped, so it never bothers calling load->read. The compiler can't really make these optimizations across translation units. LTO solves this, but it is only available on some arches. To address this, perform "pseudo-LTO" by inlining spl_load when there are one or fewer users. At the moment, there are no users, so define SPL_LOAD_USERS to be 0.

Changes in v6: - Use pseudo-LTO for spl_load - Align reads to bl_len

Changes in v5: - Load the header in spl_load as well - Don't bother trying to DMA-align the buffer, since we can't really fix it.

Changes in v4: - Fix format specifiers in debug prints - Reword/fix some of the doc comments for spl_load

Changes in v3: - Fix using ffs instead of fls - Fix using not initializing bl_len when info->filename was NULL

Changes in v2: - Use reverse-xmas-tree style for locals in spl_simple_read. This is not complete, since overhead depends on bl_mask.

This converts the nand load method to use spl_load. nand_page_size may not be valid until after nand_spl_load_image is called (see e.g. fsl_ifc_spl), so we set bl_len in spl_nand_read. Since spl_load reads the header for us, we can remove that argument from spl_nand_load_element.

There are two possible regressions which could result from this commit. First, we ask for a negative address from spl_get_load_buffer. That is, instead of

header = spl_get_load_buffer(0, sizeof(*header));

we do

header = spl_get_load_buffer(-sizeof(*header), sizeof(*header));

this could cause a problem if spl_get_load_buffer does not return valid memory for negative offsets. Second, we now set bl_len for legacy images. This can cause memory up to a bl_len - 1 before the image load address to be written, which might not have been the case before. If this turns out to be a problem, we can add an option for a bounce buffer.

We can't load FITs with external data with SPL_LOAD_FIT_FULL, so disable the test in that case. No boards enable SPL_NAND_SUPPORT and SPL_LOAD_FIT_FULL, so this is not a regression.

This converts the semihosting load method to use spl_load. As a result, it also adds support for LOAD_FIT_FULL and IMX images.

spi_load_image_os performs almost the same steps as the non-falcon-boot path of spl_spi_load_image. The load address is different, and it also loads a device tree, but that's it. Refactor the boot process so that they can both use the same load function.
