This is meant to allow for different canary values per task. On ARM, GCC expects the canary value to be found in a global variable called __stack_chk_guard. So this variable has to be updated with the value stored in the task struct whenever a task switch occurs. Because the variable GCC expects is global, this cannot work on SMP unfortunately. So, on SMP, the same initial canary value is kept throughout, making this feature a bit less effective although it is still useful. One way to overcome this GCC limitation would be to locate the __stack_chk_guard variable into a memory page of its own for each CPU, and then use TLB locking to have each CPU see its own page at the same virtual address for each of them.

Strictly, this covers the memory type (strongly ordered, device, memory), cache attributes (uncached, write combine, write through, write back read alloc, write back write alloc) and the shared bit. However, using ioremap() and its variants on system RAM results in mappings which differ in these attributes from the main system RAM mapping. Other architectures which similar restrictions approch this problem in the same way - they do not permit ioremap on main system RAM. Make ARM behave in the same way, with a WARN_ON() such that users can be traced and an alternative approach found.

There is no substitute for MACH_MX2 as most usages of MX2 only means MX21 + MX27 but not MX25. Later the choice about CPU and CPU family should go away and the individual machines should select the right SOC symbol. This is a precondition to support more than one SOC in a single kernel image.

AT91SAM9263 and AT91SAM9G45 family have tow SDRAM or DDR/SDRAM controllers. Power management should take care of this. This patch modify the way RAM IP header files are implemented to allow access to registers of both controllers ; it also adds some macros. We also modify the power management files to use those modified header files. Slow clock (assembly) and regular power management functions are synchronized for setting of RAM self-refresh procedure: (lpr & ~AT91_DDRSDRC_LPCB) | AT91_DDRSDRC_LPCB_SELF_REFRESH Note that AT91RM9200 is not impacted by this modification.

The register to read this status directly is removed on the PB1176. - Define the UART3 on the DevChip (where is actually is) and define the new UART4 serial port on the FPGA. - Also define the clocks for these two UARTs apropriately. - Remove the false notion that the PB1176 should have its CLCD on the ISSP, this is not the case, it is in the DevChip. - Remove the defintions and the previously commented-out PL081 DMAC. As confirmed by mail this was found to be broken on the PB1176 board and removed from the subsequent FPGA images.

With these changes in place, it makes the code much easier to understand and hence easier to convert to LMB.

This was done to match the original DNS-323 firmware which blinks during the boot process and sets the LED to solid when booting has completed. However, the downside of this behaviour is that it requires userland code to change the LED, even for those who don't care about the behaviour of the original firmware. Therefore, change it to solid again and let those who care about the original behaviour change the behaviour from userland.

TS-219 MPP44 can be used to differentiate between one-bay (TS-11x) and two-bay (TS-21x) devices. According to an engineer from QNAP, the setting of MPP44 depends on the firmware rather than hardware. Presumably, this means that you could fake the MPP44 value by changing the boot loader.
