      [ARM] nommu: defines CPU_CP15, CPU_CP15_MMU and CPU_CP15_MPU · fefdaa06
      Hyok S. Choi 提交于
      By merging of uClinux/ARM, we need to treat various CPU cores which have
      MMU, MPU or even none for memory management. The memory management
      coprocessors are controlled by CP15 register set and the ARM core family
      can be categorized by 5 groups by the register ;
        G-a. CP15 is MMU : 610, 710, 720, 920, 922, 925, 926, 1020, 1020e, 1022,
      		v6 and the derivations sa1100, sa110, xscale, xsc3.
        G-b. CP15 is MPU : 740, 940, 946, 996, 1156.
        G-c. CP15 is MPU or MMU : 1026 (selectable by schematic design)
        G-d. CP15 is exist, but nothing for memory managemnt : 966, 968.
        G-e. no-CP15 : 7tdmi, 9tdmi, 9e, 9ej
      
      This patch defines CPU_CP15, CPU_CP15_MMU and CPU_CP15_MPU. Thus the
      family can be defined as :
        - CPU_CP15 only : G-d
        - CPU_CP15_MMU(implies CPU_CP15) : G-a, G-c(selectable)
        - CPU_CP15_MPU(implies CPU_CP15) : G-b, G-c(selectable)
        - !CPU_CP15 : G-e

      [ARM] nommu: allows to support module in nommu · 6a570b28
      Hyok S. Choi 提交于
      A simple patch to support module in nommu mode.
      The vmalloc is used instead of __vmalloc_area which depends on CONFIG_MMU.
