2018-09-23efi_loader: file: support creating a directoryAKASHI Takahiro
In efi world, there is no obvious "mkdir" interface, instead, Open() with EFI_FILE_MODE_CREATE in mode parameter and EFI_FILE_DIRECTORY in attributes parameter creates a directory. In this patch, efi_file_open() is extended so as to accept such a combination of parameters and call u-boot's mkdir interface for expected action. Signed-off-by: AKASHI Takahiro <takahiro.akashi@linaro.org> Signed-off-by: Alexander Graf <agraf@suse.de>
2018-09-23cmd: fat: add fatmkdir commandAKASHI Takahiro
In this patch, a new command, fatmkdir, is added. Please note that, as there is no notion of "current directory" on u-boot, a directory name specified must contains an absolute directory path as a parent directory. Otherwise, "/" (root directory) is assumed. Signed-off-by: AKASHI Takahiro <takahiro.akashi@linaro.org> Signed-off-by: Alexander Graf <agraf@suse.de>
2018-09-23fs: fat: support mkdirAKASHI Takahiro
In this patch, mkdir support is added to FAT file system. A newly created directory contains only "." and ".." entries. Signed-off-by: AKASHI Takahiro <takahiro.akashi@linaro.org> Signed-off-by: Alexander Graf <agraf@suse.de>
2018-09-23fs: fat: remember the starting cluster number of directoryAKASHI Takahiro
The starting cluster number of directory is needed to initialize ".." (parent directory) entry when creating a new directory. Signed-off-by: AKASHI Takahiro <takahiro.akashi@linaro.org> Signed-off-by: Alexander Graf <agraf@suse.de>
2018-09-23fs: add mkdir interfaceAKASHI Takahiro
"mkdir" interface is added to file operations. This is a preparatory change as mkdir support for FAT file system will be added in next patch. Signed-off-by: AKASHI Takahiro <takahiro.akashi@linaro.org> Signed-off-by: Alexander Graf <agraf@suse.de>
2018-09-23cmd: fat: add offset parameter to fatwriteAKASHI Takahiro
In this patch, fatwrite command is extended so as to accept an additional parameter of file offset. Signed-off-by: AKASHI Takahiro <takahiro.akashi@linaro.org> Signed-off-by: Alexander Graf <agraf@suse.de>
2018-09-23fs: fat: support write with non-zero offsetAKASHI Takahiro
In this patch, all the necessary code for allowing for a file offset at write is implemented. What plays a major roll here is get_set_cluster(), which, in contrast to its counterpart, set_cluster(), only operates on already-allocated clusters, overwriting with data. So, with a file offset specified, set_contents() seeks and writes data with set_get_cluster() until the end of a file, and, once it reaches there, continues writing with set_cluster() for the rest. Please note that a file will be trimmed as a result of write operation if write ends before reaching file's end. This is an intended behavior in order to maintain compatibility with the current interface. Signed-off-by: AKASHI Takahiro <takahiro.akashi@linaro.org> Signed-off-by: Alexander Graf <agraf@suse.de>
2018-09-23fs: fat: refactor write interface for a file offsetAKASHI Takahiro
The current write implementation is quite simple: remove existing clusters and then allocating new ones and filling them with data. This, inevitably, enforces always writing from the beginning of a file. As the first step to lift this restriction, fat_file_write() and set_contents() are modified to accept an additional parameter, file offset and further re-factored so that, in the next patch, all the necessary code will be put into set_contents().

2018-09-23fs: fat: support write with sub-directory pathAKASHI Takahiro
In this patch, write implementation is overhauled and rewritten by making full use of directory iterator. The obvious bonus is that we are now able to write to a file with a directory path, like /A/B/C/FILE. Please note that, as there is no notion of "current directory" on u-boot, a file name specified must contain an absolute directory path. Otherwise, "/" (root directory) is assumed.

2018-09-23fs: fat: write returns error code instead of -1AKASHI Takahiro
It would be good that FAT write function return error code instead of just returning -1 as fat_read_file() does. This patch attempts to address this issue although it is 'best effort (or estimate)' for now. Signed-off-by: AKASHI Takahiro <takahiro.akashi@linaro.org> Signed-off-by: Alexander Graf <agraf@suse.de>
2018-09-23fs: fat: check and normalize file nameAKASHI Takahiro
FAT file system's long file name support is a bit complicated and has some restrictions on its naming. We should be careful about it especially for write as it may easily end up with wrong file system. normalize_longname() check for the rules and normalize a file name if necessary. Please note, however, that this function is yet to be extended to fully comply with the standard.

2018-09-23fs: fat: assure iterator's ->dent belongs to ->clustAKASHI Takahiro
In my attempt to re-work write operation, it was revealed that iterator's "clust" does not always point to a cluster to which a current directory entry ("dent") belongs. This patch assures that it is always true by adding "next_clust" which is used solely for dereferencing a cluster chain.

2018-09-23fs: fat: handle "." and ".." of root dir correctly with fat_itr_resolve()AKASHI Takahiro
FAT's root directory does not have "." nor ".." So care must be taken when scanning root directory with fat_itr_resolve(). Without this patch, any file path starting with "." or ".." will not be resolved at all. Signed-off-by: AKASHI Takahiro <takahiro.akashi@linaro.org> Signed-off-by: Alexander Graf <agraf@suse.de>
2018-09-23fs: fat: extend get_fs_info() for write useAKASHI Takahiro

2018-09-23ARM: tegra: reserve unmapped RAM so EFI doesn't use itStephen Warren
Tegra U-Boot ensures that board_get_usable_ram_top() never returns a value over 4GB, since some peripherals can't access such addresses. However, on systems with more than 2GB of RAM, RAM bank 1 does describe this extra RAM, so that Linux (or whatever OS) can use it, subject to DMA limitations. Since board_get_usable_ram_top() points at the top of RAM bank 0, the memory locations describes by RAM bank 1 are not mapped by U-Boot's MMU configuration, and so cannot be used for anything. For some completely inexplicable reason, U-Boot's EFI support ignores the value returned by board_get_usable_ram_top(), and EFI memory allocation routines will return values above U-Boot's RAM top. This causes U-Boot to crash when it accesses that RAM, since it isn't mapped by the MMU. One use-case where this happens is TFTP download of a file on Jetson TX1 (p2371-2180). This change explicitly tells the EFI code that this extra RAM should not be used, thus avoiding the crash. A previous attempt to make EFI honor board_get_usable_ram_top() was rejected. So, this patch will need to be replicated for any board that implements board_get_usable_ram_top().

2018-09-23efi: sandbox: Tidy up copy_fdt() to work with sandboxSimon Glass
At present this function takes a pointer as its argument, then passes this to efi_allocate_pages(), which actually takes an address. It uses casts, which are not supported on sandbox. Also the function calculates the FDT size rounded up to the neared EFI page size, then its caller recalculates the size and adds a bit more to it. This function is much better written as something that works with addresses only, and returns both the address and the size of the relocated FDT. Also, copy_fdt() returns NULL on error, but really should propagate the error from efi_allocate_pages(). To do this it needs to return an efi_status_t, not a void *. Update the code in this way, so that it is easier to follow, and also supports sandbox. Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Alexander Graf <agraf@suse.de>
