This is the storage the machine boots from by default. The partitioning
|
|
|
b03622d |
is taken from the U-Boot that is shipped with the board. There is some
|
|
|
b03622d |
more space on the flash that isn't used.

The PSCI area should be reserved in Linux for PSCI operations such as
|
|
|
b03622d |
suspend/resume.
|
|
|
b03622d |
|
|
|
b03622d |
Reserve 2MiB of memory which matches the area used by ATF (BL1, BL2,
|
|
|
b03622d |
BL3x, see [1] in ATF source code). This covers all PSCI code and data
|
|
|
b03622d |
area and is 2MiB aligned, which is required by Linux for huge pages
|
|
|
b03622d |
handling.
