* MIPS: Netlogic: Platform NAND/NOR flash supportGanesan Ramalingam2012-07-242-1/+221
| | | | | | | | | | | Changes to add support for the boot NOR flash on XLR boards and the boot NAND/NOR flash drivers on the XLS boards.

| | | | | | | | | | | Add USB initialization code, setup resources and add USB platform driver in mips/netlogic/xlr/platform.c. Add USB support for XLR/XLS platform in Kconfig.

* MIPS: Netlogic: Remove NETLOGIC_ prefixJayachandran C2012-07-241-1/+1
| | | | | | | | | | | | | Remove NETLOGIC_ prefix from gpio register definitions, this will bring it in-line with the other Netlogic headers. Having NETLOGIC prefix here is misleading because these are XLR/XLS specific register definitions.

* MIPS: Netlogic: SMP wakeup code updateJayachandran C2012-07-241-5/+42
| | | | | | | | | | | | | | | Update for core intialization code. Initialize status register after receiving NMI for CPU wakeup. Add the low level L1D flush code before enabling threads in core. Also convert the ehb to _ehb so that it works under more GCC versions.

* MIPS: Netlogic: Fix TLB size of boot CPU.Jayachandran C2012-07-031-1/+7
| | | | | | | | | | | | | | Starting other threads in the core will change the number of TLB entries of a CPU. Re-calculate current_cpu_data.tlbsize on the boot cpu after enabling and waking up other threads. The secondary CPUs do not need this logic because the threads are enabled on the secondary cores at wakeup and before cpu_probe.

* MIPS: Netlogic: Mark Netlogic chips as SMT capableHillf Danton2011-12-071-4/+7
| | | | | | | | | | | | | | | | | | | Netlogic XLR chip has multiple cores. Each core includes four integrated hardware threads, and they share L1 data and instruction caches. If the chip is marked to be SMT capable, scheduler then could do more, say, idle load balancing. Changes are now confined only to the code of XLR, and hardware is probed to get core ID for correct setup.

* MIPS: Netlogic: Merge some of XLR/XLP wakup codeJayachandran C2011-12-0710-222/+207
| | | | | | | | | | | | | | | | | | Create a common NMI and reset handler in smpboot.S and use this for both XLR and XLP. In the earlier code, the woken up CPUs would busy wait until released, switch this to wakeup by NMI. The initial wakeup code or XLR and XLP are differ since they are started from different bootloaders (XLP from u-boot and XLR from netlogic bootloader). But in both platforms the woken up CPUs wait and are released by sending an NMI. Add support for starting XLR and XLP in 1/2/4 threads per core.

| | | | | | | | | | | | | | | | | | | | | | | Usage of these flags has been deprecated for nearly 4 years by: commit f77bf01425b11947eeb3b5b54685212c302741b8 Author: Sam Ravnborg <sam@neptun.(none)> Date: Mon Oct 15 22:25:06 2007 +0200 kbuild: introduce ccflags-y, asflags-y and ldflags-y Moreover, these flags (at least EXTRA_CFLAGS) have been documented for command line use. By default, gmake(1) do not override command line setting, so this is likely to result in build failure or unexpected behavior. Replace their usage by Kbuild's `{as,cc,ld}flags-y'.
