; The following line needs to be removed for target hardware
GBLL CFG_Template
; If you want to supply a custom set of initial vectors (including reset vector) include the following line
; GBLL CFG_CustomVectors
;
; and provide a custom_vectors.inc file
; 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.

; 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.
;

; 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.
