88 DMA mapping framework by default aligns all buffers to the smallest
89 PAGE_SIZE order which is greater than or equal to the requested buffer
90 size. This works well for buffers up to a few hundreds kilobytes, but
91 for larger buffers it just a waste of address space. Drivers which has
92 relatively small addressing window (like 64Mib) might run out of
93 virtual space with just a few allocations.
94
95 With this parameter you can specify the maximum PAGE_SIZE order for
96 DMA IOMMU buffers. Larger buffers will be aligned only to this
97 specified order. The order is expressed as a power of two multiplied
98 by the PAGE_SIZE.

127 The Extended Industry Standard Architecture (EISA) bus was

129
130 The EISA bus provided some of the features of the IBM MicroChannel
131 bus while maintaining backward compatibility with cards made for
132 the older ISA bus. The EISA bus saw limited use between 1988 and
133 1995 when it was made obsolete by the PCI bus.

1307 PL310 implements the Clean & Invalidate by Way L2 cache maintenance
1308 operation (offset 0x7FC). This operation runs in background so that
1309 PL310 can handle normal accesses while it is in progress. Under very
1310 rare circumstances, due to this erratum, write data can be lost when
1311 PL310 treats a cacheable write transaction during a Clean &
1312 Invalidate by Way operation.

1344
1345 Under some condition the effect of cache sync operation on
1346 the store buffer still remains when the operation completes.
1347 This means that the store buffer is always asked to drain and
1348 this prevents it from merging any further writes. The workaround
1349 is to replace the normal offset of cache sync operation (0x730)
1350 by another offset targeting an unmapped PL310 register 0x740.
1351 This has the same effect as the cache sync operation: store buffer
1352 drain and waiting for all buffers empty.

1686 Various binutils versions can resolve Thumb-2 branches to
1687 locally-defined, preemptible global symbols as short-range "b.n"
1688 branch instructions.
1689
1690 This is a problem, because there's no guarantee the final
1691 destination of the symbol, or any candidate locations for a
1692 trampoline, are within range of the branch. For this reason, the
1693 kernel does not support fixing up the R_ARM_THM_JUMP11 (102)
1694 relocation in modules at all, and it makes little sense to add
1695 support.
1696
1697 The symptom is that the kernel fails with an "unsupported
1698 relocation" error when loading some modules.
1699
1700 Until fixed tools are available, passing
1701 -fno-optimize-sibling-calls to gcc should prevent gcc generating
1702 code which hits this problem, at the cost of a bit of extra runtime
1703 stack usage in some cases.

2060 Execute-In-Place allows the kernel to run from non-volatile storage
2061 directly addressable by the CPU, such as NOR flash. This saves RAM
2062 space since the text section of the kernel is not loaded from flash
2063 to RAM. Read-write sections, such as the data section and stack,
2064 are still copied to RAM. The XIP kernel is not compressed since
2065 it has to run directly from flash, so it will take more space to
2066 store it. The flash address used to link the kernel object files,
2067 and for storing it, is configuration dependent. Therefore, if you
2068 say Y here, you must know the proper physical address where to
2069 store the kernel image depending on your own flash memory usage.

2071 Also note that the make target becomes "make xipImage" rather than
2072 "make zImage" or "make Image". The final kernel binary to put in
