2015-05-11[libcpu][am335x] Fix the booting failure when enabling MMUAdrian Huang
Since the 16 domains are configured as the client domains in mmu_setttbase(), a Permission fault is generated if the XN bit (Execute-never) is set in the short-descriptor translation table (for section and supersection). This leads to the booting failure when enabling MMU for beagleboard bsp. Here is log: ---------------------------------------------------------------- SD/MMC found on device 0 reading uEnv.txt 117 bytes read in 3 ms (38.1 KiB/s) Loaded environment from uEnv.txt Importing environment from mmc ... Running uenvcmd ... reading rtthread.bin 162624 bytes read in 24 ms (6.5 MiB/s) \## Starting application at 0x80200000 ... ---------------------------------------------------------------- This commit removes the XN bit configuration in the section of the short-descriptor translation table. The OS can be booted successfully with applying this commit.

This piece of code will enable the interrupt early before switching to the first thread. Although it is harmless, but not prefect.

Unit of "byte" is more intuitive than "long".
2013-11-17cortex-r4: let svc mode reuse the stack of IRQ on startupGrissiom
As the svc stack is the stack of threads, there is no need to allocate a separate stack for the startup. Reuse the IRQ stack should be OK. Tested on rm48 board.
2013-11-04Fix hardfault bug for gcc portBright Pan
for 2013-02-20 aozima commmit "port for gcc", but the commit is not tested,and the kernel is breakdown in context_gcc.S, the file is a copy from cortex-m3,but not port for cortex-m0, so i complete this port for aozima, test it in stm32f0discovery board , and it works fine.
