+
+; If you want to supply a custom set of initial vectors (including reset vector) include the following line

+; Variant Number, just an example:
+ INIT_NUMERIC_CONSTANT CFG_HWVD, 0x09080001
+
+; On ARM architecture 6 processors, include the following line to override the threshold
+; on total physical RAM size at which the multiple memory model switches into large address space mode
+; i.e. size>threshold -> 2Gb per process, size<=threshold -> 1Gb per process
+; Defaults to 32Mb.
+; INIT_NUMERIC_CONSTANT CFG_ARMV6_LARGE_CONFIG_THRESHOLD, <value>
+
+; For the direct memory model only, include the following line if you wish the exception vectors at the
+; start of the bootstrap to be used at all times. This is only relevant if an MMU is present - this option
+; is mandatory if not.
+; GBLL CFG_UseBootstrapVectors
+;
+; If the above option is in use (including if no MMU is present) the following symbol should be defined
+; to specify the offset from the bootstrap to the kernel image.
+ INIT_NUMERIC_CONSTANT KernelCodeOffset, 0x4000
+
+; Include the following line if you wish to include the ROM autodetection code based on data bus
+; capacitance and image repeats.
+; GBLL CFG_AutoDetectROM
+
+; Include the following line to minimise the initial kernel heap size
+; On the direct memory model the size of the kernel data area (super page to end of kernel heap)
+; is rounded up to the next 1Mb if this is not included, 4K if it is.
+; On the moving and multiple models, the size of the initial kernel heap area is rounded up to
+; the next 64K if this is not included, 4K if it is.
+; GBLL CFG_MinimiseKernelHeap
+
+; Include the following line if default memory mapping should use shared memory.
+; Should be defined on multicore (SMP) devices.
+; GBLL CFG_USE_SHARED_MEMORY
+
+; On the moving or multiple memory models, include either or both of the following lines to
+; specify the size of the initial kernel heap
+; INIT_NUMERIC_CONSTANT CFG_KernelHeapMultiplier, <multiplier>
+; INIT_NUMERIC_CONSTANT CFG_KernelHeapBaseSize, <base>
+;
+; The initial kernel heap size is MAX( <base> + <multiplier> * N / 16, value specified in ROMBUILD )
+; where N is the total physical RAM size in pages.
+; <base> defaults to 24K and <multiplier> defaults to 9*16 (ie 9 bytes per page).
+
+; Uncomment if using ARM1136 processor and ARM1136 Erratum 353494
+; "Rare conditions can cause corruption of the Instruction Cache"
+; is fixed on this hardware.
+;
+; NOTE: The boot table should use this macro to determine whether RONO or RORO permissions
+; are used for the exception vectors. If the erratum is not fixed, RORO must be used.
+;
+; GBLL CFG_CPU_ARM1136_ERRATUM_353494_FIXED

+; Uncomment if using ARM1136 processor and ARM1136 Erratum 364296
+; "Possible Cache Data Corruption with Hit-Under-Miss"
+; is fixed on this hardware.
+;
+; GBLL CFG_CPU_ARM1136_ERRATUM_364296_FIXED
+
+; Uncomment if using ARM1136 processor and ARM1136 Erratum 399234
+; "Write back data cache entry evicted by write through entry causes data corruption"
+; is fixed on this hardware.
+; Workaround
+; The erratum may be avoided by marking all cacheable memory as one of write through or write back.
+; This requires the memory attributes described in the translation tables to be modified by software
+; appropriately, or the use of the remapping capability to remap write through regions to non cacheable.
+;
+; If this macro is enabled, it should be accompanied by:
+; "macro __CPU_ARM1136_ERRATUM_399234_FIXED" in variant.mmh
+; GBLL CFG_CPU_ARM1136_ERRATUM_399234_FIXED
+
+
+; Uncomment if:
+; 1) using ARM1136 processor and ARM1136 Erratum 411920: "Invalidate Entire Instruction Cache
+; operation might fail to invalidate some lines if coincident with linefill"
+; is fixed on this hardware, or
+; 2) using ARM1176 processor and ARM1176 Erratum 415045: "Invalidate Entire Instruction Cache
+; operation might fail to invalidate some lines if coincident with linefill
+; is fixed on this hardware.
+; Workaround:
+; 1) Disables the use of of prefetch range cache operations by setting RV bit in Auxiliary Ctrl Reg.
+; 2) Replaces Invalidate ICache operation with the sequence defined in the errata document.
+; If this macro is enabled, it should be accompanied by:
+; "macro __CPU_ARM1136_ERRATUM_411920_FIXED" in variant.mmh

+; Uncomment if using ARM1136 processor and ARM1136 Erratum 415662: "Invalidate Instruction Cache by

+; Disables the use of of prefetch range cache operations by setting RV bit in Auxiliary Ctrl Reg.
