100 The EISA bus provided some of the features of the IBM MicroChannel
101 bus while maintaining backward compatibility with cards made for
102 the older ISA bus. The EISA bus saw limited use between 1988 and
103 1995 when it was made obsolete by the PCI bus.

1221 (r1p0..r1p2) erratum. If a code sequence containing an ARM/Thumb
1222 interworking branch is replaced with another code sequence at the

1301 r2p0) erratum. A faulty ASID can be sent to the other CPUs for the
1302 broadcasted CP15 TLB maintenance operations TLBIASIDIS and TLBIMVAIS.
1303 As a consequence of this erratum, some TLB entries which should be
1304 invalidated are not, resulting in an incoherency in the system page
1305 tables. The workaround changes the TLB flushing routines to invalidate
1306 entries regardless of the ASID.

1348 Under some condition the effect of cache sync operation on
1349 the store buffer still remains when the operation completes.
1350 This means that the store buffer is always asked to drain and
1351 this prevents it from merging any further writes. The workaround
1352 is to replace the normal offset of cache sync operation (0x730)
1353 by another offset targeting an unmapped PL310 register 0x740.
1354 This has the same effect as the cache sync operation: store buffer
1355 drain and waiting for all buffers empty.

1660 default y
1661 help
1662 Various binutils versions can resolve Thumb-2 branches to
1663 locally-defined, preemptible global symbols as short-range "b.n"
1664 branch instructions.
1665
1666 This is a problem, because there's no guarantee the final
1667 destination of the symbol, or any candidate locations for a
1668 trampoline, are within range of the branch. For this reason, the
1669 kernel does not support fixing up the R_ARM_THM_JUMP11 (102)
1670 relocation in modules at all, and it makes little sense to add
1671 support.
1672
1673 The symptom is that the kernel fails with an "unsupported
1674 relocation" error when loading some modules.
1675
1676 Until fixed tools are available, passing
1677 -fno-optimize-sibling-calls to gcc should prevent gcc generating
1678 code which hits this problem, at the cost of a bit of extra runtime
1679 stack usage in some cases.
1680
1681 The problem is described in more detail at:
1682 https://bugs.launchpad.net/binutils-linaro/+bug/725126

2030 On some architectures (EBSA110 and CATS), there is currently no way
2031 for the boot loader to pass arguments to the kernel. For these
2032 architectures, you should supply some command-line options at build
2033 time by entering them here. As a minimum, you should specify the
2034 memory size and the root device (e.g., mem=64M root=/dev/nfs).

2066 Execute-In-Place allows the kernel to run from non-volatile storage
2067 directly addressable by the CPU, such as NOR flash. This saves RAM
2068 space since the text section of the kernel is not loaded from flash
2069 to RAM. Read-write sections, such as the data section and stack,
2070 are still copied to RAM. The XIP kernel is not compressed since
2071 it has to run directly from flash, so it will take more space to
2072 store it. The flash address used to link the kernel object files,
2073 and for storing it, is configuration dependent. Therefore, if you
2074 say Y here, you must know the proper physical address where to
2075 store the kernel image depending on your own flash memory usage.

2077 Also note that the make target becomes "make xipImage" rather than
2078 "make zImage" or "make Image". The final kernel binary to put in
