* sandbox: block driver using host file/device as backing storeHenrik Nordström2014-01-08-0/+5
| | | | | | | | | | | | | | | | | | | 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.

* Fix ext2/ext4 filesystem accesses beyond 2TiBFrederic Leroy2013-07-15-2/+2
| | | | | | | | | | | | | | | | | With CONFIG_SYS_64BIT_LBA, lbaint_t gets defined as a 64-bit type, which is required to represent block numbers for storage devices that exceed 2TiB (the block size usually is 512B), e.g. recent hard drives We now use lbaint_t for partition offset to reflect the lbaint_t change, and access partitions beyond or crossing the 2.1TiB limit. This required changes to signature of ext4fs_devread(), and type of all variables relatives to block sector. ext2/ext4 fs uses logical block represented by a 32 bit value. Logical block is a multiple of device block sector. To avoid overflow problem when calling ext4fs_devread(), we need to cast the sector parameter. Signed-off-by: Frédéric Leroy <fredo@starox.org>
* Fix block device accesses beyond 2TiBSascha Silbe2013-06-26-3/+3
| | | | | | | | | | | | | | | | | | With CONFIG_SYS_64BIT_LBA, lbaint_t gets defined as a 64-bit type, which is required to represent block numbers for storage devices that exceed 2TiB (the block size usually is 512B), e.g. recent hard drives. For some obscure reason, the current U-Boot code uses lbaint_t for the number of blocks to read (a rather optimistic estimation of how RAM sizes will evolve), but not for the starting address. Trying to access blocks beyond the 2TiB boundary will simply wrap around and read a block within the 0..2TiB range. We now use lbaint_t for block start addresses, too. This required changes to all block drivers as the signature of block_read(), block_write() and block_erase() in block_dev_desc_t changed. Signed-off-by: Sascha Silbe <t-uboot@infra-silbe.de>
* part/dev_desc: Add log2 of blocksize to block_dev_desc data structEgbert Eich2013-05-01-0/+5
| | | | | | | | | | log2 of the device block size serves as the shift value used to calculate the block number to read in file systems when implementing avaiable block sizes. It is needed quite often in file systems thus it is pre-calculated and stored in the block device descriptor. Signed-off-by: Egbert Eich <eich@suse.com>
* disk/gpt: Fix GPT partition handling for blocksize != 512Egbert Eich2013-05-01-0/+4
| | | | | | | | Disks beyond 2T in size use blocksizes of 4096 bytes. However a lot of code in u-boot still assumes a 512 byte blocksize. This patch fixes the handling of GPTs. Signed-off-by: Egbert Eich <eich@suse.com>

* disk: part_efi: parse and store partition UUIDStephen Warren2012-09-25-0/+3
| | | | | | | | | | | 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 Warren2012-09-25-4/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Signed-off-by: Rob Herring <rob.herring@calxeda.com> [swarren: Rob implemented scanning for bootable partitions. I fixed a couple of issues there, switched the syntax to ":auto", added the error-checking rework, and ":0" syntax for the whole device] Signed-off-by: Stephen Warren <swarren@nvidia.com>
* disk: introduce get_device()Stephen Warren2012-09-25-0/+5
| | | | | | | | | 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/+11
| | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | Mflash is fusion memory device mainly targeted consumer eletronic and mobile phone. Internally, it have nand flash and other hardware logics and supports some different operation (ATA, IO, XIP) modes. IO mode is custom mode for the host that doesn't have IDE interface. (Many mobile targeted SoC doesn't have IDE bus) This driver support mflash IO mode. Followings are brief descriptions about IO mode. 1. IO mode based on ATA protocol and uses some custom command. (read confirm, write confirm) 2. IO mode uses SRAM bus interface. Signed-off-by: unsik Kim <donari75@gmail.com>

* fix pxa255_idp boardMarcel Ziswiler2007-10-23-3/+3
| | | | | | | | | | | | | | | | | | | | | | | The pxa255_idp being an old unmaintained board showed several issues: 1. CONFIG_INIT_CRITICAL was still defined. 2. Neither CONFIG_MAC_PARTITION nor CONFIG_DOS_PARTITION was defined. 3. Symbol flash_addr was undeclared. 4. The boards lowlevel_init function was still called memsetup. 5. The TEXT_BASE was still 0xa3000000 rather than 0xa3080000. 6. Using -march=armv5 instead of -march=armv5te resulted in lots of 'target CPU does not support interworking' warnings on recent compilers. 7. The PXA's serial driver redefined FFUART, BTUART and STUART used as indexes rather than the register definitions from the pxa-regs header file. Renamed them to FFUART_INDEX, BTUART_INDEX and STUART_INDEX to avoid any ambiguities. 8. There were several redefinition warnings concerning ICMR, OSMR3, OSCR, OWER, OIER, RCSR and CCCR in the PXA's assembly start file. 9. The board configuration file was rather outdated. 10. The part header file defined the vendor, product and revision arrays as unsigned chars instead of just chars in the block_dev_desc_t structure. Signed-off-by: Marcel Ziswiler <marcel@ziswiler.com>
