As an alternative to this I experimenting with
```
CONFIG_SAMV7_OTA_PRIMARY_SLOT_OFFSET=0x24000
CONFIG_SAMV7_OTA_SCRATCH_OFFSET=0x74000
CONFIG_SAMV7_OTA_SCRATCH_SIZE=0x6000
CONFIG_SAMV7_OTA_SECONDARY_SLOT_OFFSET=0x4C000
```
So basically update `boards/arm/samv7/common/Kconfig` to:
```
if SAMV7_FORMAT_MCUBOOT
comment "MCUboot Application Image OTA Update support"
config SAMV7_OTA_PRIMARY_SLOT_OFFSET
hex "MCUboot application image primary slot offset"
default 0x24000
config SAMV7_OTA_PRIMARY_SLOT_DEVPATH
string "Application image primary slot device path"
default "/dev/ota0"
config SAMV7_OTA_SECONDARY_SLOT_OFFSET
hex "MCUboot application image secondary slot offset"
default 0x4C000 if SAMV7_MEM_FLASH_512
default 0x84000 if SAMV7_MEM_FLASH_1024
default 0x104000 if SAMV7_MEM_FLASH_2048
config SAMV7_OTA_SECONDARY_SLOT_DEVPATH
string "Application image secondary slot device path"
default "/dev/ota1"
config SAMV7_OTA_SLOT_SIZE
hex "MCUboot application image slot size (in bytes)"
default 0x28000 if SAMV7_MEM_FLASH_512
default 0x60000 if SAMV7_MEM_FLASH_1024
default 0xe0000 if SAMV7_MEM_FLASH_2048
config SAMV7_OTA_SCRATCH_OFFSET
hex "MCUboot scratch partition offset"
default 0x74000 if SAMV7_MEM_FLASH_512
default 0xe4000 if SAMV7_MEM_FLASH_1024
default 0x1e4000 if SAMV7_MEM_FLASH_2048
config SAMV7_OTA_SCRATCH_DEVPATH
string "Scratch partition device path"
default "/dev/otascratch"
config SAMV7_OTA_SCRATCH_SIZE
hex "MCUboot scratch partition size (in bytes)"
default 0x6000 if SAMV7_MEM_FLASH_512
default 0x1C000
endif # SAMV7_FORMAT_MCUBOOT
```
so basically extend MCUboot loader maximum size from 128K to 144K. What do
you think?
