config LINKER_HOME_AREA
hex "Physical start of _HOME area"
default 0x0000
---help---
Physical address of the start of the linker HOME area. Default: 0x0000
config LINKER_CODE_AREA
hex "Physical start of _CODE area"
default 0x0200
---help---
Physical address of the start of the linker _CODE area. Default: 0x0200
config LINKER_DATA_AREA
hex "Physical start of _DATA area"
default 0x8000
---help---
Physical address of the start of the linker _DATA area. Default: 0x8000
config LINKER_ROM_AT_0000
bool "ROM at Physical 0x0000"
default n
---help---
Some architectures may have ROM located at physical address zero. In this
case, a special version of the "head" file must be used.
config Z180_BANKAREA_VIRTBASE
hex "Virtual Start of Bank Area"
default 0x8000
---help---
This setting provides the virtual address of the start of the Bank Area.
NOTE that 0x0000 <= Z180_BANKAREA_BASE <= Z180_COMMONAREA_BASE is required!
Default: 0x8000
NuttX Memory Organization:
Common Area 0: This area holds the common NuttX code that is
directly call-able from all application threads. Common Area
always starts at virtual address 0x0000 and extends to the
Bank Area
Base Area: This area holds the common NuttX data (including the
share-able heap) that is accessible from all applications and
extends to Common Area 1.
NOTE: That is execution from RAM, the common NuttX code and
data may be contiguous and lie in the same region (either
Common Area 0 or the Bank Area). The two regions above would
apply in a ROM'ed system, where Common Area 1 is ROM and the
Base Area is RAM.
Common Area 1: This area holds the code and data that is unique
to a particular task. his area extends to the end of the virtual
address space. All tasks share the same virtual Common Area 2
virtual address (but each has a unique mapping to different,
underlying physical addresses).
config Z180_BANKAREA_PHYSBASE
hex "Physical Start of Bank Area"
default 0x08000
---help---
This setting provides the physical address of the start of the Bank Area.
Default: 0x08000
config Z180_COMMON1AREA_VIRTBASE
hex "Virtual Start of Common Area 1"
default 0xc000
---help---
This setting provides the virtual address of the start of the Common
Area 1. NOTE that 0x0000 <= Z180_BANKAREA_BASE <= Z180_COMMONAREA_BASE
is required! Default: 0xc000

virtual address (but each has a unique mapping to different,

config Z180_PHYSHEAP_START
hex "Physical Start of Free Memory"
default 0x0c000
---help---
This setting provides the physical address of the start of free physical
memory that will be used to allocate memory for tasks (Common Area 1).
Default: 0x0c000
config Z180_PHYSHEAP_END
hex "Physical End(+1) of Free Memory"
default 0x100000
---help---
This setting provides the physical address of the end(+1) of free physical
memory that will be used to allocate memory for tasks (Common Area 1).
Default: 0x100000
config ARCH_HAVEHEAD
bool "Board-specific Head File"
default n
---help---
Use a board-specific version of the "head" file in the
configs/<board-name>/src directory
