There are a bunch of patches to remove some stuff. Some of those may become optional (through settings) so security and features are available in the full system, but a slimmer version is available in boot.img.

Fix build on big endian systems
|
|
|
|
The usb_linux_client.c file defines cpu_to_le16/32 by using the C
|
|
library htole16/32 function calls. However, cpu_to_le16/32 are used
|
|
when initializing structures, i.e in a context where a function call
|
|
is not allowed.
|
|
|
|
It works fine on little endian systems because htole16/32 are defined
|
|
by the C library as no-ops. But on big-endian systems, they are
|
|
actually doing something, which might involve calling a function,
|
|
causing build failures.
|
|
|
|
To solve this, we simply open-code cpu_to_le16/32 in a way that allows
|
|
them to be used when initializing structures.
