* cmd: gpt: fix the wrong size parse for the last partitionKever Yang2016-08-05-0/+4
| | | | | | | | | | | The calculation of "dev_desc->lba - 34 - 1 - offset" is not correct for size '-', because both fist_usable_lba and last_usable_lba will remain 34 sectors. We can simply use 0 for size '-' because the part_efi module will decode the size and auto extend the size to maximum available size. Signed-off-by: Kever Yang <kever.yang@rock-chips.com>

* drivers: block: add block device cacheEric Nelson2016-04-01-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a block device cache to speed up repeated reads of block devices by various filesystems. This small amount of cache can dramatically speed up filesystem operations by skipping repeated reads of common areas of a block device (typically directory structures). This has shown to have some benefit on FAT filesystem operations of loading a kernel and RAM disk, but more dramatic benefits on ext4 filesystems when the kernel and/or RAM disk are spread across multiple extent header structures as described in commit fc0fc50. The cache is implemented through a minimal list (block_cache) maintained in most-recently-used order and count of the current number of entries (cache_count). It uses a maximum block count setting to prevent copies of large block reads and an upper bound on the number of cached areas. The maximum number of entries in the cache defaults to 32 and the maximum number of blocks per cache entry has a default of 2, which has shown to produce the best results on testing of ext4 and FAT filesystems. The 'blkcache' command (enabled through CONFIG_CMD_BLOCK_CACHE) allows changing these values and can be used to tune for a particular filesystem layout. Signed-off-by: Eric Nelson <eric@nelint.com>

* dm: part: Convert partition API use to linker listsSimon Glass2016-03-14-142/+114
| | | | | | | | | | | | | | | | | | | We can use linker lists instead of explicitly declaring each function. This makes the code shorter by avoiding switch() statements and lots of header file declarations. While this does clean up the code it introduces a few code issues with SPL. SPL never needs to print partition information since this all happens from commands. SPL mostly doesn't need to obtain information about a partition either, except in a few cases. Add these cases so that the code will be dropped from each partition driver when not needed. This avoids code bloat. I think this is still a win, since it is not a bad thing to be explicit about which features are used in SPL. But others may like to weigh in.

| | | | | | | | | | | | | | | | | On bootup the emmc's hw partition is always set to 0 and the partition table is read from it. When switching to another hw partition the partition table's id is not updated but instead the old one from hw partition 0 is used. If there is no partition table on hw partition 0 then the code will terminate and return error even if the desired hw partition contains a perfectly fine partition table.

* gpt: Fix the protective MBR partition sizeMaxime Ripard2015-01-08-1/+1
| | | | | | | | | | | | | | According to the UEFI Spec (Table 16, section 5.2.3 of the version 2.4 Errata B), the protective MBR partition record size must be set to the size of the disk minus one, in LBAs. However, the current code was setting the size as the total number of LBAs on the disk, resulting in an off-by-one error. This confused the AM335x ROM code, and will probably confuse other tools as well. Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com>
