1224 (r1p0..r1p2) erratum. If a code sequence containing an ARM/Thumb
1225 interworking branch is replaced with another code sequence at the

1227 to physical address re-mapping, Cortex-A8 does not recover from the

1305 broadcasted CP15 TLB maintenance operations TLBIASIDIS and TLBIMVAIS.
1306 As a consequence of this erratum, some TLB entries which should be
1307 invalidated are not, resulting in an incoherency in the system page
1308 tables. The workaround changes the TLB flushing routines to invalidate
1309 entries regardless of the ASID.

1351 Under some condition the effect of cache sync operation on
1352 the store buffer still remains when the operation completes.
1353 This means that the store buffer is always asked to drain and
1354 this prevents it from merging any further writes. The workaround
1355 is to replace the normal offset of cache sync operation (0x730)
1356 by another offset targeting an unmapped PL310 register 0x740.
1357 This has the same effect as the cache sync operation: store buffer
1358 drain and waiting for all buffers empty.

1663 default y
1664 help
1665 Various binutils versions can resolve Thumb-2 branches to
1666 locally-defined, preemptible global symbols as short-range "b.n"
1667 branch instructions.
1668
1669 This is a problem, because there's no guarantee the final
1670 destination of the symbol, or any candidate locations for a
1671 trampoline, are within range of the branch. For this reason, the
1672 kernel does not support fixing up the R_ARM_THM_JUMP11 (102)
1673 relocation in modules at all, and it makes little sense to add
1674 support.
1675
1676 The symptom is that the kernel fails with an "unsupported
1677 relocation" error when loading some modules.
1678
1679 Until fixed tools are available, passing
1680 -fno-optimize-sibling-calls to gcc should prevent gcc generating
1681 code which hits this problem, at the cost of a bit of extra runtime
1682 stack usage in some cases.
1683
1684 The problem is described in more detail at:
1685 https://bugs.launchpad.net/binutils-linaro/+bug/725126

2033 On some architectures (EBSA110 and CATS), there is currently no way
2034 for the boot loader to pass arguments to the kernel. For these
2035 architectures, you should supply some command-line options at build
2036 time by entering them here. As a minimum, you should specify the
2037 memory size and the root device (e.g., mem=64M root=/dev/nfs).

2069 Execute-In-Place allows the kernel to run from non-volatile storage
2070 directly addressable by the CPU, such as NOR flash. This saves RAM
2071 space since the text section of the kernel is not loaded from flash
2072 to RAM. Read-write sections, such as the data section and stack,
2073 are still copied to RAM. The XIP kernel is not compressed since
2074 it has to run directly from flash, so it will take more space to
2075 store it. The flash address used to link the kernel object files,
2076 and for storing it, is configuration dependent. Therefore, if you
2077 say Y here, you must know the proper physical address where to
2078 store the kernel image depending on your own flash memory usage.
2079
2080 Also note that the make target becomes "make xipImage" rather than
2081 "make zImage" or "make Image". The final kernel binary to put in
