Merge branch 'remove' of master.kernel.org:/home/rmk/linux-2.6-arm
* 'remove' of master.kernel.org:/home/rmk/linux-2.6-arm:
ARM: 6629/2: aaec2000: remove support for mach-aaec2000
ARM: lh7a40x: remove unmaintained platform support
Fix up trivial conflicts in
- arch/arm/mach-{aaec2000,lh7a40x}/include/mach/memory.h (removed)
- drivers/usb/gadget/Kconfig (USB_[GADGET_]LH7A40X removed, others added)

213 | /* The LPD7X_IOBARRIER is necessary to overcome a mismatch between the | ||
214 | * way that the CPU handles chip selects and the way that the SMC chip | ||
215 | * expects the chip select to operate. Refer to | ||
216 | * Documentation/arm/Sharp-LH/IOBarrier for details. The read from | ||
217 | * IOBARRIER is a byte, in order that we read the least-common | ||
218 | * denominator. It would be wasteful to read 32 bits from an 8-bit | ||
219 | * accessible region. | ||
220 | * | ||
221 | * There is no explicit protection against interrupts intervening | ||
222 | * between the writew and the IOBARRIER. In SMC ISR there is a | ||
223 | * preamble that performs an IOBARRIER in the extremely unlikely event | ||
224 | * that the driver interrupts itself between a writew to the chip an | ||
225 | * the IOBARRIER that follows *and* the cache is large enough that the | ||
226 | * first off-chip access while handing the interrupt is to the SMC | ||
227 | * chip. Other devices in the same address space as the SMC chip must | ||
228 | * be aware of the potential for trouble and perform a similar | ||
229 | * IOBARRIER on entry to their ISR. | ||
