; Description:  

;

; NE1_TBVariant bootstrap configuration file

; Include to enable tracing

;	GBLL	CFG_DebugBootRom

; Include to initialise debug port in bootstrap without enabling bootstrap

; trace. Useful for __EARLY_DEBUG__ mode.

;	GBLL	CFG_InitDebugPort

; Include one of these to select the CPU

	GBLL	CFG_CPU_ARM11MP

; Include the following line if this is a bootloader bootstrap

;	GBLL	CFG_BootLoader

; 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

	INIT_NUMERIC_CONSTANT	CFG_HWVD, 0x09080001

; 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 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

; 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:

; 		"#define __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:

; 	"#define __CPU_ARM1136_ERRATUM_411920_FIXED" in variant.mmh

;

;	GBLL	CFG_CPU_ARM1136_ERRATUM_411920_FIXED

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

; Index might corrupt cache when used with background prefetch range" is fixed on this hardware.

; Workaround:

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

;

;	GBLL	CFG_CPU_ARM1136_ERRATUM_415662_FIXED

; Uncomment if this variant config needs to support the Shadow Memory Regions

; (SMR) feature in the kernel. Basically allows media based images to be copied

; into memory which is later reserved by the Kernel RAM Allocator. 

; One user of the SMR feature is the HCR component when used with media based 

; setting repository. Thus variant configs that support the new MHA HCR 

; component and expect media based settings must define this macro e.g. NAND 

; Core Image ROM, but not BootLoader ROM etc.
