At present block devices are tied up with partitions. But not all block
devices have partitions within them. They are in fact separate concepts.

Create a separate blk.h header file for block devices.

This will allow the implementation to make use of data in the block_dev
structure beyond the base device number. This will be useful so that eMMC
block devices can encompass the HW partition ID rather than treating this
out-of-band. Equally, the existence of the priv field is crying out for
this patch to exist.

clang chokes about the concept of having an alias to an
always_inlined function. gcc likely just ignores the always
inlined since binary sizes are equal before and after this
patch. Convert the aliases to weak functions and provide
missing prototypes.

Add a const keyword to the sect_buf argument of
ide_write_data to fix the following warning:

  cmd_ide.c: In function '__ide_output_data':
  cmd_ide.c:548: warning: passing argument 2 of 'ide_write_data' discards qualifiers from pointer target type
  /devel/u-boot.git/include/ide.h:76: note: expected 'ulong *' but argument is of type 'const ulong *'

Also modify the driver-model documentation to
match with the new prototype.

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.

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.

move most of mpc8xx hooks from cmd_ide.c into ide_preinit() and newly created
ide_init_postreset() (invoked after calling ide_reset after ide_preinit),
some cleanup to make checkpatch happy, enable IDE init hooks in configs of
affected boards.
confusingly, these hooks are used by more than just mpc8xx-based boards, and
therefore are placed in arch/ppc/lib/

note: checkpatch still emits warnings about using volatile

The IDE_BUS(dev) macro was previously doing dev >> 1.  This however is a
mis-match of the usage in common/cmd_ide.c and would cause boards with
multiple ports / devices to not correctly detect all devices.  For more

Although most IDE controller is designed to be connected to PCI bridge,
there are still some IDE controller support AHB interface for SoC design.

The driver implementation of these IDE-AHB controllers differ from other
IDE-PCI controller, some additional registers and commands access is required
during CMD/DATA I/O. Hence a configuration "CONFIG_IDE_AHB" in cmd_ide.c is
required to be defined to support these kinds of SoC controllers. Such as
Faraday's FTIDE020 series and Global Unichip's UINF-0301.

U-Boot can detect if an IDE device is present or not.
If not, and this new config option is activated, U-Boot
removes the ATA node from the DTS before booting Linux,
so the Linux IDE driver does not probe the device and
crash. This is needed for buggy hardware (uc101) where
no pull down resistor is connected to the signal IDE5V_DD7.
