Subject: [PATCH 1/2] Add initial support of ARC architecture
|
|
|
|
DesignWare ARC 700 and ARC HS38 are families of 32-bit CPUs
|
|
developed by Synopsys, Inc.
|
|
|
|
This change implements following:
|
|
[1] Defines ARC as one embedded targets
|
|
[2] Defines default tools prefixed for ARC like
|
|
arc-linux-g++ etc
|
|
[3] Defines "inotify" syscall numbers for ARC
|
|
(note ARC fully compliant to Linux UAPI headers)
|
|
[4] Disables 16-bit aligned data access
|
|
|
|
For now we're using generic atomic ops even though it may
|
|
introduce performance panalty.
|
|
|
|
Change-Id: I91e879ac55c2f3643a544f97cd59671a81ccc3c2
|
|
|
|
This patch was submited in upstream Qt4 and if it ever gets accepted,
|
|
it should be removed from Buildroot.
