2021-07-28disk: Tidy up #ifdefs in part_efiSimon Glass1-5/+6
This file does not correctly handle the various cases, sometimes producing warnings about partition_basic_data_guid being defined but not used. Fix it. There was some discussion about adjusting Kconfig or making HAVE_BLOCK_DEVICE a prerequisite for PARTITIONS, but apparently this is not feasible. Such changes can be undertaken separate from the goal of this series. Signed-off-by: Simon Glass <sjg@chromium.org>

2021-05-27part: Add check for NULL dev_part_strSean Anderson1-1/+5
Some callers (e.g. cmd/fs.c) of fs_set_blk_dev may use a NULL dev_part_str. While blk_get_device_part_str handles this fine, part_get_info_by_dev_and_name does not. This fixes commands crashing when implicitly using bootdevice. The unit test has also been updated to set bootdevice to a known value and to restore it after we are done.

There's no reason to require an appropriately sized output parameter for the string, that's error-prone should the table ever grow an element with a longer string. We can just return the const char* pointer directly. Update the only caller accordingly, and get rid of pointless ifdeffery in the header so that the compiler always sees a declaration and can thus do type-checking, whether or not PARTITION_TYPE_GUID is enabled or not.

2020-03-18sunxi: Move common defconfig options to KconfigAndre Przywara1-0/+2
Some config symbols are found in *almost* every _defconfig file for Allwinner boards, because those options are actually a platform choice, and not a per-board decision. Some of these options are older, some have recently been added. Move those options to be set for all Allwinner boards in their respective Kconfig files. The rationales are as follows: - NR_DRAM_BANKS: All Allwinner SoC map DRAM at one contiguous region of address space only, starting at 1 GB. So it's always one bank. - SPL_{DOS,EFI}_PARTITION: The Allwinner SPL does only support raw MMC accesses, we don't care about filesystems or partitions in there, so there is no need to define those symbols at all. - USE_PREBOOT: We start USB early when a keyboard is configured, using the preboot env variable, so we need to set this variable. - SYS_RELOC_GD_ENV_ADDR: We don't specify any ENV_ADDR, so need this symbol to be set (according to 8d8ee47e03e). - SYS_USB_EVENT_POLL_VIA_INT_QUEUE: According to commit eab9433aa55428, specifying this reduces the latency of the USB keyboard handling, so this was formerly enabled in config headers for all Allwinner boards.

2019-10-31disk: part_dos: correctly detect DOS PBRHeinrich Schuchardt1-14/+25
The signature 0x55 0xAA in bytes 510 and 511 of the first sector can either indicate a DOS partition table of the first sector of a FAT file system. The current code tries to check if the partition table is valid by looking at the boot indicator of the partition entries. But first of all it does not count from 0 to 3 but only from 0 to 2. And second it misses to increment the pointer for the partition entry. If it is a FAT file system can be discovered by looking for the text 'FAT' at offset 0x36 or 'FAT32' at offset 0x52. In a DOS PBR there are no partition entries, so those bytes are undefined. Don't require the byte at offset 0x1BE to differ from 0x00 and 0x80. With the patch the logic is changed as follows: If the partition table has either an invalid boot flag for any partition or has no partition at all, check if the first sector is a DOS PBR by looking at the FAT* signature.
