boot/startup: Update generated linker script for newt size
Autogenerated linker script have BOOT and SLOT0 regions
specified to avoid potential inconsistency between bootloader
and application code.
Fragment of generated linker script for application:
MEMORY
{
BOOT (rx!w) : ORIGIN = 0x08000000, LENGTH = 131072
SLOT0 (rx!w) : ORIGIN = 0x08020000, LENGTH = 786432
RAM (rwx) : ORIGIN = (0x24000000), LENGTH = ((0x80000) - (768))
STACK_RAM (rw) : ORIGIN = (0x24000000) + (0x80000) - (768), LENGTH =
(768)
}
SECTIONS
{
...
.interrupts :
{
...
__isr_vector_end = .;
} > SLOT0
.text :
{
...
} > SLOT0
SLOT0 is used as destination instead of customary FLASH
For bootloader build regions would be the same but destination
would be > BOOT
This however confuses newt size that expect FLASH as destination
when used with newt size -F
This modifies generated linker script in a way that regions
now have FLASH instead of BOOT or SLOT0 depending on build type
MEMORY
{
BOOT (rx!w) : ORIGIN = 0x08000000, LENGTH = 131072
FLASH (rx!w) : ORIGIN = 0x08020000, LENGTH = 786432
RAM (rwx) : ORIGIN = (0x24000000), LENGTH = ((0x80000) - (768))
STACK_RAM (rw) : ORIGIN = (0x24000000) + (0x80000) - (768), LENGTH =
(768)
}
SECTIONS
{
...
.interrupts :
{
...
__isr_vector_end = .;
} > FLASH
.text :
{
...
} > FLASH
