[ARM] nommu: defines CPU_CP15, CPU_CP15_MMU and CPU_CP15_MPU
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)

[ARM] nommu: defines CPU_CP15, CPU_CP15_MMU and CPU_CP15_MPU
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)

The Intel StrongARM(R) SA-110 is a 32-bit microprocessor and
|
|
|
|
is available at five speeds ranging from 100 MHz to 233 MHz.
|
|
|
|
More information is available at
|
|
|
|
<http://developer.intel.com/design/strong/sa110.htm>.
|
|
|
|
|
|
|
|
Say Y if you want support for the SA-110 processor.
|
|
|
|
Otherwise, say N.

[ARM] nommu: defines CPU_CP15, CPU_CP15_MMU and CPU_CP15_MPU
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

This enables the kernel to use some instructions not present

[ARM] nommu: defines CPU_CP15, CPU_CP15_MMU and CPU_CP15_MPU
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

(depending on the model) one or two Feroceon CPU cores with 512K of L2
cache and VFP coprocessors running at (depending on the model) between
800 MHz and 1.2 GHz, and features a DDR2 controller, two PCIe
interfaces that can each run either in x4 or quad x1 mode, three USB
2.0 interfaces, two 3Gb/s SATA II interfaces, a SPI interface, two
TWSI interfaces, a crypto accelerator, IDMA/XOR engines, a SPI
interface, four UARTs, and depending on the model, two or four gigabit
ethernet interfaces.
This patch adds basic support for the platform, and allows booting
on the MV78x00 development board, with functional UARTs, SATA, PCIe,
GigE and USB ports.
