d96a98045a disk/part.c: Expose list of available block drivers
We have a pretty nice and generic interface to ask for a specific block
device. However, that one is still based around the magic notion that
we know the driver name.

In order to be able to write fully generic disk access code, expose the
currently internal list to other source files so that they can scan through
all available block drivers.

96e5b03c8a dm: part: Convert partition API use to linker lists
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.

99e7fc8a26 mmc: emmc and hw partitions partition table id bugfix.
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. This fix updates
the partition table struct to correspond to the specified hw partition
before testing if the partition table is valid or not.

cfdaf4caa2 part:efi: add bootable parameter in gpt command
The optional parameter bootable is added in gpt command to set the
partition attribute flag "Legacy BIOS bootable"

This flag is used in extlinux and so in with distro to select
the boot partition where is located the configuration file
(please check out doc/README.distro for details).

With this parameter, U-Boot can be used to create the boot partition
needed for device using distro.

example of use:

setenv partitions "name=u-boot,size=60MiB;name=boot,size=60Mib,bootable;\
                   name=rootfs,size=0"

> gpt write mmc 0 $partitions

> part list mmc 0

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.

6825a95b0b kbuild: use Linux Kernel build scripts
Now we are ready to switch over to real Kbuild.

This commit disables temporary scripts:
  scripts/{Makefile.build.tmp, Makefile.host.tmp}
and enables real Kbuild scripts:
  scripts/{Makefile.build,Makefile.host,Makefile.lib}.

This switch is triggered by the line in scripts/Kbuild.include
  -build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build.tmp obj
  +build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build obj

We need to adjust some build scripts for U-Boot.
But smaller amount of modification is preferable.

Additionally, we need to fix compiler flags which are
locally added or removed.

In Kbuild, it is not allowed to change CFLAGS locally.
Instead, ccflags-y, asflags-y, cppflags-y,
CFLAGS_$(basetarget).o, CFLAGS_REMOVE_$(basetarget).o
are prepared for that purpose.

the variable log2blksz is not initialized, which it's not correct.

04735e9c55 Fix ext2/ext4 filesystem accesses beyond 2TiB
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.

or DOS partition name. This situation is happening:

part.h:     disk_partition_t->name is 32-byte long
part_efi.h: gpt_entry->partition_name is 36-bytes long

The loop in part_efi.c copies over 36 bytes and thus accesses beyond
the disk_partition_t->name .

Fix this by picking the shortest of source and destination arrays and
make sure the destination array is cleared so the trailing bytes are
zeroed-out and don't cause issues with string manipulation.

9d956e0fef disk/part_dos: check harder for partition table
Devices that used to have a whole disk FAT filesystem but got then
partitioned will most likely still have a FAT or FAT32 signature
in the first sector as this sector does not get overwritten by
a partitioning tool (otherwise the tool would risk to kill the mbr).

The current partition search algorithm will erronously detects such
a device as a raw FAT device.

Instead of looking for the FAT or FAT32 signatures immediately we
use the same algorithm as used by the Linux kernel and first check
for a valid boot indicator flag on each of the 4 partitions.
If the value of this flag is invalid for the first entry we then
do the raw partition check.
If the flag for any higher partition is wrong we assume the device
is neiter a MBR nor PBR device.

d1efb6442a disk: part_dos: don't claim whole-disk FAT filesystems
Logically, a disk that contains a raw FAT filesystem does not in fact
have a partition table. However, test_part_dos() was claiming that such
disks did in fact have a DOS-style partition table. This caused
get_device_and_partition() not to return a whole-disk disk_partition_t,
since part_type != PART_TYPE_UNKNOWN.

part_dos.c's print_partition_extended() detected the raw FAT filesystem
condition and printed a fake partition table that encompassed the whole
disk.

However, part_dos.c's get_partition_info_extended() did not return any
valid partitions in this case. This combination caused
get_device_and_partition() not to find any valid partitions, and hence
to return an error.

Fix test_part_dos() not to claim that raw FAT filesystems are DOS
partition tables. In turn, this causes get_device_and_partition() to
return a whole-disk disk_partition_t, and hence the following commands
work:

fatls mmc 0 /
fatls mmc 0:auto /

An alternative would be to modify print_partition_extended() to detect
raw FAT filesystems, just like print_partition_extended() does, and to
return a fake partition in this case. However, this seems logically
incorrect, and also duplicates code, since get_device_and_partition()
falls back to returning a whole-disk partition when there is no partition
table on the device.

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.

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.

This fix simply ensures that get_dev returns NULL when invoked
with a NULL ifname.

4715a81136 disk: part_efi: fix regression due to incorrect buffer usage
Commit deb5ca8027 "disk: part_efi: fix
**pgpt_pte == NULL" modified the code to pass "&gpt_head" to
is_gpt_valid() rather than the previous "gpt_head". However, gpt_head
is a pointer to the buffer, not the actual buffer, since it was allocated
using ALLOC_CACHE_ALIGN_BUFFER. This caused is_gpt_valid() to read the
disk block onto the stack rather than into the buffer, causing the
code to fail.

This change reverts that portion of the commit mentioned above.

Currently part_efi.c allocates buffers for the gpt_header, the

This patch uses ALLOC_CACHE_ALIGN_BUFFER for the stack allocated

6d8962e814 Switch from archive libraries to partial linking
Before this commit, weak symbols were not overridden by non-weak symbols
found in archive libraries when linking with recent versions of
binutils.  As stated in the System V ABI, "the link editor does not
extract archive members to resolve undefined weak symbols".

This commit changes all Makefiles to use partial linking (ld -r) instead
of creating library archives, which forces all symbols to participate in
linking, allowing non-weak symbols to override weak symbols as intended.
This approach is also used by Linux, from which the gmake function
cmd_link_o_target (defined in config.mk and used in all Makefiles) is
inspired.

The name of each former library archive is preserved except for
extensions which change from ".a" to ".o".  This commit updates
references accordingly where needed, in particular in some linker
scripts.

This commit reveals board configurations that exclude some features but
include source files that depend these disabled features in the build,
resulting in undefined symbols.  Known such cases include:
- disabling CMD_NET but not CMD_NFS;
- enabling CONFIG_OF_LIBFDT but not CONFIG_QE.

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

This patch re-introduces the missing test for unknown device types.

  2) Set environement variable BUILD_DIR to point to the desired location
  'export BUILD_DIR=/tmp/build'
  'make'

The second approach can also be used with a MAKEALL script
'export BUILD_DIR=/tmp/build'
'./MAKEALL'

Command line 'O=' setting overrides BUILD_DIR environent variable.

When none of the above methods is used the local build is performed and
the object files are placed in the source directory.
