-/*
- * At present, all PowerPC 400-class processors share a similar TLB
- * architecture. The instruction and data sides share a unified,
- * 64-entry, fully-associative TLB which is maintained totally under
- * software control. In addition, the instruction side has a
- * hardware-managed, 4-entry, fully-associative TLB which serves as a
- * first level to the shared TLB. These two TLBs are known as the UTLB
- * and ITLB, respectively (see "mmu.h" for definitions).
- *
- * There are several potential gotchas here.  The 40x hardware TLBLO
- * field looks like this:
- *
- * 0  1  2  3  4  ... 18 19 20 21 22 23 24 25 26 27 28 29 30 31
- * RPN.....................  0  0 EX WR ZSEL.......  W  I  M  G
- *
- * Where possible we make the Linux PTE bits match up with this
- *
- * - bits 20 and 21 must be cleared, because we use 4k pages (40x can
- *   support down to 1k pages), this is done in the TLBMiss exception
- *   handler.
- * - We use only zones 0 (for kernel pages) and 1 (for user pages)
- *   of the 16 available.  Bit 24-26 of the TLB are cleared in the TLB
- *   miss handler.  Bit 27 is PAGE_USER, thus selecting the correct
- *   zone.
- * - PRESENT *must* be in the bottom two bits because swap cache
- *   entries use the top 30 bits.  Because 40x doesn't support SMP
- *   anyway, M is irrelevant so we borrow it for PAGE_PRESENT.  Bit 30
- *   is cleared in the TLB miss handler before the TLB entry is loaded.
- * - All other bits of the PTE are loaded into TLBLO without
- *   modification, leaving us only the bits 20, 21, 24, 25, 26, 30 for
- *   software PTE bits.  We actually use bits 21, 24, 25, and
- *   30 respectively for the software bits: ACCESSED, DIRTY, RW, and
- *   PRESENT.

CONFIG_4xx was corresponding to CONFIG_40x | CONFIG_44x.

As CONFIG_40x is gone, CONFIG_4xx and CONFIG_44x are now equivalent.
And CONFIG_BOOKE is also set when CONFIG_44x is set.

Replace (CONFIG_4xx | CONFIG_BOOKE) by CONFIG_BOOKE
Replace other CONFIG_4xx by CONFIG_44x
Remove CONFIG_4xx.
