* sandbox: block driver using host file/device as backing storeHenrik Nordström2014-01-08-0/+6
| | | | | | | | | | | | | | | | | | | Provide a way to use any host file or device as a block device in U-Boot. This can be used to provide filesystem access within U-Boot to an ext2 image file on the host, for example. The support is plumbed into the filesystem and partition interfaces. We don't want to print a message in the driver every time we find a missing device. Pass the information back to the caller where a message can be printed if desired.

* fs/ext4: fix log2blksz un-initialized error, by cacaulating its value from blkszLan Yixun (dlan)2013-07-22-0/+4
| | | | | | | | | | | The problem here is that uboot can't mount ext4 filesystem with commit "50ce4c07df1" applied. We use hard-coded "SECTOR_SIZE"(512) before this commit, now we introduce (block_dev_desc_t *)->log2blksz to replace this macro. And after we calling do_ls()->fs_set_blk_dev(), the variable log2blksz is not initialized, which it's not correct. And this patch try to solve the problem by caculating the value of log2blksz from variable blksz.

* part: check each variable for capability calculationJerry Huang2012-12-06-1/+1
| | | | | | | | | | | In order to calculate the capability, we use the below expression to check: ((dev_desc->lba * dev_desc->blksz)>0L) If the capability is greater than 4GB (e.g. 8GB = 8 * 1024 * 104 * 1024), the result will overflow, the low 32bit may be zero. Therefore, change to check each variable to fix this potential issue. Signed-off-by: Jerry Huang <Chang-Ming.Huang@freescale.com>
* disk: Make the disk partition code work with no specific partition typesGabe Black2012-10-22-33/+17
| | | | | | | | | | | | | | | Currently, if the disk partition code is compiled with all of the parition types compiled out, it hits an #error which stops the build. This change adjusts that file so that those functions will fall through to their defaults in those cases instead of breaking the build. These functions are needed because other code calls them, and that code is needed because other config options are overly broad and bring in support we don't need along with support we do. Also reduce repetition of the 6-term #ifdef throughout the file. Signed-off-by: Gabe Black <gabeblack@chromium.org> Signed-off-by: Simon Glass <sjg@chromium.org>
* disk: initialize name/part fields when returning a whole diskStephen Warren2012-10-19-0/+2
| | | | | | | | | | | | | | | | | | When get_device_and_partition() finds a disk without a partition table, under some conditions, it "returns" a disk_partition_t that describes the entire raw disk. Make sure to initialize all fields in the partition descriptor in that case. The value chosen for name is just some arbitrary descriptive string. The value chosen for info matches the check at the end of get_device_and_partition(). However, it's probably not that important; it's not obvious that the value is really used.

* disk: get_device_and_partition() return value fixesStephen Warren2012-10-17-1/+1
| | | | | | | | | | | When no valid partitions are found, guarantee that we return -1. This most likely already happens, since the most recent get_partition_info() will have returned an error. However, it's best to be explicit. Remove an unnecessary assignment of ret=0 in the success case; this value is over-written with the processed partition ID later.

* disk: part_efi: parse and store partition UUIDStephen Warren2012-09-25-0/+5
| | | | | | | | | | | Each EFI partition table entry contains a UUID. Extend U-Boot's struct disk_partition to be able to store this information, and modify get_partition_info_efi() to fill it in. The implementation of uuid_string() was derived from the Linux kernel, tag v3.6-rc4 file lib/vsprintf.c function uuid_string(). Signed-off-by: Stephen Warren <swarren@nvidia.com>
* disk: get_device_and_partition() "auto" partition and cleanupStephen Warren2012-09-25-43/+154
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rework get_device_and_partition() to: a) Implement a new partition ID of "auto", which requests that U-Boot search for the first "bootable" partition, and fall back to the first valid partition if none is found. This way, users don't need to specify an explicit partition in their commands. b) Make use of get_device(). c) Add parameter to indicate whether returning a whole device is acceptable, or whether a partition is mandatory. d) Make error-checking of the user's device-/partition-specification more complete. In particular, if strtoul() doesn't convert all characters, it's an error rather than just ignored. The resultant device/partition returned by the function will be as follows, based on whether the disk has a partition table (ptable) or not, and whether the calling command allows the whole device to be returned or not. (D and P are integers, P >= 1) D D: No ptable: !allow_whole_dev: error allow_whole_dev: device D ptable: device D partition 1 D:0 !allow_whole_dev: error allow_whole_dev: device D D:P No ptable: error ptable: device D partition P D:auto No ptable: !allow_whole_dev: error allow_whole_dev: device D ptable: first partition in device D with bootable flag set. If none, first valid paratition in device D. Note: In order to review this patch, it's probably easiest to simply look at the file contents post-application, rather than reading the patch itself.

* disk: introduce get_device()Stephen Warren2012-09-25-0/+22
| | | | | | | | | This patch introduces function get_device(). This looks up a block_dev_desc_t from an interface name (e.g. mmc) and device number (e.g. 0). This function is essentially the non-partition-specific prefix of get_device_and_partition(). Signed-off-by: Stephen Warren <swarren@nvidia.com>
* disk/part: introduce get_device_and_partitionRob Herring2012-09-25-2/+67
| | | | | | | | | | | | All block device related commands (scsiboot, fatload, ext2ls, etc.) have simliar duplicated device and partition parsing and selection code. This adds a common function to replace various implementations. The new function has an enhancement over current versions. If no device or partition is specified on the command line, the bootdevice env variable will be used (scsiboot does this). Signed-off-by: Rob Herring <rob.herring@calxeda.com>
* disk: make get_partition_info() always available to disk.cStephen Warren2012-09-25-55/+63
| | | | | | | | | | | | | | | | | | | | | | | | Now that get_device_and_partition() always calls get_partition_info() when disk.c is compiled, we must always compile the function, rather than ifdef it away. The implementation must be conditional based on CONFIG_CMD_* etc., since that's what e.g. part_dos.c uses to ifdef out get_partition_info_dos(); CONFIG_DOS_PARTITION can be enabled even without those commands being enabled. Technically, this change is required before Rob's "disk/part: introduce get_device_and_partition" patch. However, at least when the compiler optimizer is turned on, it isn't required before then in practice, since get_device_and_partition() calls get_dev(), which is stubbed out in disk.c under exactly the same conditions that get_partition_info() is not compiled, and hence the compiler never generates code for the call to the missing function. However, in my later patch "disk: get_device_and_partition() "auto" partition and cleanup", the optimizer doesn't succeed at this, and may attempt to reference the undefined function.

* disk/part.c: Fix device enumeration through APITim Kientzle2012-03-27-0/+3
| | | | | | | | | | | | | | | The patch below fixes device enumeration through the U-Boot API. Device enumeration crashes when the system in question doesn't have any RAM mapped to address zero (I discovered this on a BeagleBone board), since the enumeration calls get_dev with a NULL ifname sometimes which then gets passed down to strncmp(). This fix simply ensures that get_dev returns NULL when invoked with a NULL ifname. Signed-off-by: Tim Kientzle <kientzle@freebsd.org> Signed-off-by: Anatolij Gustschin <agust@denx.de>

* IDE: bail out of dev_print() for unknown device typesWolfgang Denk2009-05-15-0/+5
| | | | | | | | | | | | | | | | | | | | | Commit 574b319512 introduced a subtle bug by mixing a list of tests for "dev_desc->type" and "dev_desc->if_type" into one switch(), which then mostly did not work because "dev_desc->type" cannot take any "IF_*" type values. A later fix in commit 8ec6e332ea changed the switch() into testing "dev_desc->if_type", but at this point the initial test for unknown device types was completely lost, which resulted in output like that for IDE ports without device attached: Device 1: Model: Firm: Ser#: Type: # 1F # Capacity: not available This patch re-introduces the missing test for unknown device types.
