There are two tavorevb boards in the kernel, one using a PXA930 chip in mach-pxa, and one using the later PXA910 chip in mach-mmp. They use the same board number, which is generally a bad idea, and in a multiplatform kernel, we can end up with funny link errors like this one resulting from two boards gettting controlled by the same Kconfig symbol:
arch/arm/mach-mmp/tavorevb.o: In function `tavorevb_init': tavorevb.c:(.init.text+0x4c): undefined reference to `pxa910_device_uart1' tavorevb.c:(.init.text+0x50): undefined reference to `pxa910_device_gpio' tavorevb.o:(.arch.info.init+0x54): undefined reference to `pxa910_init_irq' tavorevb.o:(.arch.info.init+0x58): undefined reference to `pxa910_timer_init'
The mach-pxa TavorEVB seems much more complete than the mach-mmp one that supports only uart, gpio and ethernet. Further, I could find no information about the board on the internet aside from references to the Linux kernel, so I assume this was never available outside of Marvell and can be removed entirely.
There is a third board named TavorEVB in the Kconfig description, but this refers to the "TTC_DKB" machine. The two are clearly related, so I change the Kconfig description to just list both names.
