config ARMV7A_HAVE_L2CC

Selected by the configuration tool if the architecutre supports any
kind of L2 cache.

bool
default n
select ARMV7A_HAVE_L2CC
---help---
Set by architecture-specific code if the hardware supports a PL310
r3p2 L2 cache (only version r3p2 is supported).

---help---
Enable the 2 Cache Controller (L2CC) is based on the L2CC-PL310 ARM
multi-way cache macrocell, version r3p2. The addition of an on-chip
secondary cache, also referred to as a Level 2 or L2 cache, is a
method of improving the system performance when significant memory
traffic is generated by the processor.

This choice specifies the associativity of L2 cache in terms of the
number of ways. This value could be obtained by querying cache
configuration registers. However, by defining a configuration
setting instead, we can avoid using RAM memory to hold information
about properties of the memory.

by querying cache configuration registers. However, by defining a
configuration setting instead, we can avoid using RAM memory to hold
information

For use with the GNU toolchain built with the NuttX buildroot package.
This tools may be arm-nuttx-eabi- or, if ARMV7A_OABI_TOOLCHAIN is set,
arm-nuttx-elf-.

configured for arm-none-eabi-.

Most of the older buildroot toolchains are OABI and are named
arm-nuttx-elf- vs. arm-nuttx-eabi-
config ARMV7A_DECODEFIQ
bool "FIQ Handler"
default n
---help---
Select this option if your platform supports the function
arm_decodefiq(). This is used primarily to support secure TrustZone
interrupts received on the FIQ vector.
