4d907025d6 sandbox: restore ability to access host fs through standard commands
Commit 95fac6ab45 "sandbox: Use os functions to read host device tree"
removed the ability for get_device_and_partition() to handle the "host"
device type, and redirect accesses to it to the host filesystem. This
broke some unit tests that use this feature. So, revert that change. The
code added back by this patch is slightly different to pacify checkpatch.

However, we're then left with "host" being both:
- A pseudo device that accesses the hosts real filesystem.
- An emulated block device, which accesses "sectors" inside a file stored
  on the host.

In order to resolve this discrepancy, rename the pseudo device from host
to hostfs, and adjust the unit-tests for this change.

The "help sb" output is modified to reflect this rename, and state where
the host and hostfs devices should be used.

ecdd57e274 disk: default to HW partition 0 if not specified
Currently, get_device()/get_dev_hwpart() for MMC devices does not select
an explicit HW partition unless the user explicitly requests one, i.e. by
requesting device "mmc 0.0" rather than just "mmc 0". I think it makes
more sense if the default is to select HW partition 0 (main data area)
if the user didn't request a specific partition. Otherwise, the following
happens, which feels wrong:

Select HW partition 1 (boot0):
mmc dev 0 1

Attempts to access SW partition 1 on HW partition 1 (boot0), rather than
SW partition 1 on HW partition 0 (main data area):
ls mmc 0:1 /

With this patch, the second command above re-selects the main data area.

Many device types don't support HW partitions at all, so if HW partition
0 is selected (either explicitly or as the default) and there's no
select_hwpart function, we simply skip attempting to select a HW
partition.

Some MMC devices (i.e. SD cards) don't support HW partitions. However,
this patch still works, since mmc_start_init() sets the current
partition number to 0, and mmc_select_hwpart() succeeds if the requested
partition is already selected.

336b6f9048 disk: support devices with HW partitions
Some device types (e.g. eMMC) have hardware-level partitions (for eMMC,
separate boot and user data partitions). This change allows the user to
specify the HW partition they wish to access when passing a device ID to
U-Boot Commands such as part, ls, load, ums, etc.

The syntax allows an optional ".$hwpartid" to be appended to the device
name string for those commands.

Existing syntax, for MMC device 0, default HW partition ID, SW partition
ID 1:

ls mmc 0:1 /

New syntax, for MMC device 0, HW partition ID 1 (boot0), SW partition
ID 2:

ls mmc 0.1:2 /

For my purposes, this is most useful for the ums (USB mass storage
gadget) command, but there's no reason not to allow the new syntax
globally.

This patch adds the core support infra-structure. The next patch will
provide the implementation for MMC.

95fac6ab45 sandbox: Use os functions to read host device tree
At present we use U-Boot's filesystem layer to read the sandbox device tree,

f4d8de48f5 sandbox: block driver using host file/device as backing store
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

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

50ffc3b64a fs/ext4: fix log2blksz un-initialized error, by cacaulating its value from blksz
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.

0c9c8fb5ec disk: Make the disk partition code work with no specific partition types
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.

6ab6a650a4 disk: initialize name/part fields when returning a whole disk
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.

10a37fd7a4 disk: get_device_and_partition() "auto" partition and cleanup
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.

2f50164627 disk: make get_partition_info() always available to disk.c
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.

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

This fix simply ensures that get_dev returns NULL when invoked

af75a45d23 IDE: bail out of dev_print() for unknown device types
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
