Boot space translation utilizes the pre-translation address to select
the DDR controller target. However, the post-translation address will be
presented to the selected DDR controller. It is possible that the pre-
translation address selects one DDR controller but the post-translation
address exists in a different DDR controller when using certain DDR
controller interleaving modes. The device may fail to boot under these

holding a list of per pci endpoint permitted liodn offsets.
This property is useful in virtualization scenarios
that implement per pci endpoint partitioning.

calculated by the hardware, by adding these offsets
to pci controller's base liodn, stored in the
"fsl,liodn" property of its node.
The liodn offsets are interleaved to get better cache
utilization. As an example, given 3 pci controllers,

Erratum: A-004034
Affects: SRIO
Description: During port initialization, the SRIO port performs
lane synchronization (detecting valid symbols on a lane) and
lane alignment (coordinating multiple lanes to receive valid data
across lanes). Internal errors in lane synchronization and lane
alignment may cause failure to achieve link initialization at
the configured port width.
An SRIO port configured as a 4x port may see one of these scenarios:
1. One or more lanes fails to achieve lane synchronization.
Depending on which lanes fail, this may result in downtraining
from 4x to 1x on lane 0, 4x to 1x on lane R (redundant lane).
2. The link may fail to achieve lane alignment as a 4x, even
though all 4 lanes achieve lane synchronization, and downtrain
to a 1x. An SRIO port configured as a 1x port may fail to complete
port initialization (PnESCSR[PU] never deasserts) because of
scenario 1.
Impact: SRIO port may downtrain to 1x, or may fail to complete
link initialization. Once a port completes link initialization
successfully, it will operate normally.

This change adds CBFS support and some commands to use it to u-boot. These
commands are:
cbfsinit - Initialize CBFS support and pull all metadata into RAM. The end of
the ROM is an optional parameter which defaults to the standard 0xffffffff and
can be used to support multiple CBFSes in a system. The last one set up with
cbfsinit is the one that will be used.
cbfsinfo - Print information from the CBFS header.
cbfsls - Print out the size, type, and name of all the files in the current
CBFS. Recognized types are translated into symbolic names.
cbfsload - Load a file from CBFS into memory. Like the similar command for fat
filesystems, you can optionally provide a maximum size.
Support for CBFS is compiled in when the CONFIG_CMD_CBFS option is specified.
The CBFS driver can also be used programmatically from within u-boot.
If u-boot needs something out of CBFS very early before the heap is
configured, it won't be able to use the normal CBFS support which caches some
information in memory it allocates from the heap. The
cbfs_file_find_uncached function searches a CBFS instance without touching
the heap.

This patch adds support for linker-generated array. These arrays
are a generalization of the U-Boot command declaration approach.
Basically, the idea is to generate an array, where elements of the
array are statically initialized at compile time and each element
is declared separatelly at different place. Such array is assembled
together into continuous piece of memory by linker and a pointer to
it's first entry can then be retrieved via accessor.
The actual implementation relies on placing any variable that is to
represent an element of LG-array into particular subsection of the
.u_boot_list linker section . The subsection is determined by user
options. Once compiled, it is possible to dump all symbols placed
in .u_boot_list section and the subsections in which they should be
and generate appropriate bounds for each requested subsection of the
.u_boot_list section. Each such subsection thus contains __start and
__end entries at the begining and end respecitively.
This allows for simple run-time traversing of the array, since the
symbols are properly defined.
