Currently, the SRIO and PCIE boot master module will be compiled into the

macro has been included by all the corenet architecture platform boards.
But in fact, it's uncertain whether all corenet platform boards support

So it may be better to get rid of the macro "CONFIG_FSL_CORENET", and add
a special macro for every board which can support the feature. This

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.

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.

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

common: Implement support for linker-generated arrays
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.

common: Add symbol handling for generic lists into Makefile
This patch adds essential components for generation of the contents of
the linker section that is used by the linker-generated array. All of
the contents is held in a separate file, u-boot.lst, which is generated
at runtime just before U-Boot is linked.
The purpose of this code is to especially generate the appropriate
boundary symbols around each subsection in the section carrying the
linker-generated arrays. Obviously, the interim linker code for actual
placement of the variables into the section is generated too. The
generated file, u-boot.lst, is included into u-boot.lds via the linker
INCLUDE directive in u-boot.lds .
Adjustments are made in the Makefile and spl/Makefile so that the
u-boot.lds and u-boot-spl.lds depend on their respective .lst files.
