Add support for an owned buffer
When passing a data buffer back from a function, it is not always clear
who owns the buffer, i.e. who is responsible for freeing the memory used.
An example of this is where multiple files are decompressed from the
firmware image, using a temporary buffer for reading (since the
compressed data has to live somewhere) and producing a temporary or
permanent buffer with the resuilts.
Where the firmware image can be memory-mapped, as on x86, the compressed
data does not need to be buffered, but the complexity of having a buffer
which is either allocated or not, makes the code hard to understand.
Introduce a new 'abuf' which supports simple buffer operations:
- encapsulating a buffer and its size
- either allocated with malloc() or not
- able to be reliably freed if necessary
- able to be converted to an allocated buffer if needed
This simple API makes it easier to deal with allocated and memory-mapped
buffers.

Aardvark does not have a real PCIe Root Port device on the root bus.
Instead it has PCIe registers of PCIe Root Port device mapped in
internal Aardvark memory space starting at offset 0xc0.
The PCIe Root Port itself is normally available as a PCI Bridge device
on the root bus with bus number zero. Aardvark instead has the
configuration registers of this PCI Bridge at offset 0x00 of Aardvark's
memory space, but the class code of this device is Mass Storage
Controller (0x010400), instead of PCI Bridge (0x600400), which causes
U-Boot to fail to recognize it as a P2P Bridge
Add a hook into the pcie_advk_read_config() / pcie_advk_write_config()
functions to redirect access for root bus from PIO transfer to this
internal Aardvark memory space. This will allow U-Boot to access
configuration space of this PCI Bridge which represents PCIe Root Port.
Redirect access to PCI Bridge registers in range 0x10 - 0x34 to driver's
internal buffer (cfgcache[]). This is because at those addresses
Aardvark has different registers, incompatible with config space of a
PCI Bridge.
Redirect access to PCI Bridge register PCI_ROM_ADDRESS1 (0x38) to
Aardvark internal address for that register (0x30).
When reading PCI Bridge register PCI_HEADER_TYPE, set it explicitly to
value Type 1 (PCI_HEADER_TYPE_BRIDGE) as PCI Bridge must be of Type 1.
When writing to PCI_PRIMARY_BUS or PCI_SECONDARY_BUS registers on this
PCI Bridge, correctly update driver's first_busno and sec_busno
variables, so that pcie_advk_addr_valid() function can check if address
of any device behind the root bus is valid and that PIO transfers are
started with correct config type (1 vs 0), which is required for
accessing devices behind some PCI bridge after the root bus.
U-Boot's PCI_PNP code sets primary and secondary bus numbers as relative
to the configured bus number of the root bus. This is done so that
U-Boot can support multiple PCIe host bridges or multiple root port
buses, when internal bus numbers are different.
Now that root bus is available, update code in pcie_advk_read_config()
and pcie_advk_write_config() functions to correctly calculate real
Aardvark bus number of the target device from U-Boot's bus number as:
busno = PCI_BUS(bdf) - dev_seq(bus)

This code is trying to parse PCIe config space of PCIe card connected on
the other end of link and then is trying to force 5.0 GT/s speed via Target
Link Speed bits in PCIe Root Port Link Control 2 Register on the local part
of link if it sees that card supports 5.0 GT/s via Max Link Speed bits in
Link Capabilities Register.
The code is incorrect for more reasons:
- Accessing config space of an endpoint card cannot be done immediately.
If the PCIe link is not up, reading vendor/device ID registers will
return all ones.
- Parsing is incomplete, so it can cause issues even for working cards.
Moreover there is no need to force speed to 5.0 GT/s via Target Link Speed
bits on PCIe Root Port Link Control 2 Register. Hardware changes speed from
2.5 GT/s to 5.0 GT/s autonomously when it is supported.
Most importantly, this code does not change link speed at all, since
because after updating Target Link Speed bits on PCIe Root Port Link
Control 2 Register, it is required to retrain the link, and the code for
that is completely missing.
The code was probably needed for making buggy endpoint cards work. Such a
workaround, though, should be implemented via PCIe subsystem (via quirks,
for example), as buggy cards could also affect other PCIe controllers.
Note that this code is fully unrelated to a38x SerDes code and really
should not have been included in SerDes initialization. Usage of magic
constants without names and comments made this SerDes code hard to read and
understand.
Remove this PCIe application code from low level SerDes code. As this code
is configuring only 5.0 GT/s part, in the worst case, it could leave buggy
cards at the initial speed of 2.5 GT/s (if somehow before this change they
could have been "upgraded" to 5.0 GT/s speed even with missing link
retraining). Compliant cards which just need longer initialization should
work better after this change.

set/get rate functions. This also protects our other calculations from
using bogus values for rate.

Convert CONFIG_NAND_OMAP_ECCSCHEME to Kconfig
The values of CONFIG_NAND_OMAP_ECCSCHEME map to the enum in
include/linux/mtd/omap_gpmc.h for valid ECC schemes. Make which one we
will use be a choice statement, enumerating the ones which we have
implemented.

Convert CONFIG_NAND_FSL_ELBC et al to Kconfig
This converts the following to Kconfig:
CONFIG_NAND_FSL_ELBC
CONFIG_NAND_FSL_IFC
Note that a number of PowerPC platforms had previously enabled
CONFIG_NAND_FSL_ELBC without CONFIG_MTD_RAW_NAND, and now they no longer
enable the option, reducing the size of a few functions.

nand.h: Cleanup linux/mtd/rawnand.h usage
We only include <linux/mtd/rawnand.h> in <nand.h> for the forward
declaration of struct nand_chip, so do that directly. Then, include
<linux/mtd/rawnand.h> where required directly.

Convert CONFIG_SYS_NAND_BAD_BLOCK_POS to Kconfig
This converts the following to Kconfig:
CONFIG_SYS_NAND_BAD_BLOCK_POS
In order to do this, introduce a choice for HAS_LARGE/SMALL_BADBLOCK_POS
as those are the only valid values. Use LARGE as the default as no
in-tree boards use SMALL, but it is possible.

m53menlo: Switch to deriving CONFIG_SYS_NAND_PAGE_COUNT
Typically platforms will define CONFIG_SYS_NAND_PAGE_COUNT based on
CONFIG_SYS_NAND_BLOCK_SIZE / CONFIG_SYS_NAND_PAGE_SIZE. Switch to this
in preparation for migrating CONFIG_SYS_NAND namespace to Kconfig.
