2012-10-22disk: Make the disk partition code work with no specific partition typesGabe Black
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>
2012-10-19disk: initialize name/part fields when returning a whole diskStephen Warren
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.

2012-10-17disk: get_device_and_partition() return value fixesStephen Warren
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.

2012-09-28disk: allow - or empty string to fall back to $bootdeviceStephen Warren
Commit 10a37fd "disk: get_device_and_partition() "auto" partition" prevented the use of "-" on the command-line to request fallback to the $bootdevice environment variable instead. This patch allows that, or an empty string "" to be used. Tested: setenv bootfile /boot/zImage setenv bootdevice 0:1 ext2load mmc 0:1 ext2load mmc - ext2load mmc "" Signed-off-by: Stephen Warren <swarren@nvidia.com>
2012-09-25disk: part_efi: parse and store partition UUIDStephen Warren
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>
2012-09-25disk: get_device_and_partition() "auto" partition and cleanupStephen Warren
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>
2012-09-25disk: introduce get_device()Stephen Warren
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>
2012-09-25disk/part: introduce get_device_and_partitionRob Herring
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>
2012-09-25disk: make get_partition_info() always available to disk.cStephen Warren
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.

2012-03-27disk/part.c: Fix device enumeration through APITim Kientzle
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>

2009-05-15IDE: bail out of dev_print() for unknown device typesWolfgang Denk
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.

2009-04-03mflash: Initial mflash supportunsik Kim
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>
2009-03-20vsprintf: pull updates from Linux kernelMike Frysinger
This brings in support for the %p modifier which allows us to easily print out things like ip addresses, mac addresses, and pointers. It also converts the rarely used 'q' length modifier to the common 'L' modifier when dealing with quad types. While this new code is a bit larger (~1k .text), most of it should be made up by converting the existing ip/mac address code to use format modifiers. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
