2012-07-24MIPS: Netlogic: Remove NETLOGIC_ prefixJayachandran C1-1/+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.

2012-07-24MIPS: Netlogic: SMP wakeup code updateJayachandran C1-5/+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.

2012-07-24MIPS: Netlogic: Update comments in smpboot.SJayachandran C1-48/+58
No change in logic, comments update and whitespace cleanup. * A few comments in the file were in assembler style and the rest int C style, convert all of them to C style. * Mark workarounds for Ax silicon with a macro XLP_AX_WORKAROUND * Whitespace fixes - use tabs consistently * rename __config_lsu macro to xlp_config_lsu Signed-off-by: Jayachandran C <[email protected]> Cc: [email protected] Patchwork: https://patchwork.linux-mips.org/patch/3749/ Signed-off-by: Ralf Baechle <[email protected]>
2012-07-23MIPS: Prune some target specific code out of prom.cDavid Daney2-0/+35
This code is not common enough to be in a shared file. It is also not used by any existing boards, so just remove it.

2012-07-03MIPS: Netlogic: Fix TLB size of boot CPU.Jayachandran C1-1/+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.

2011-12-07MIPS: Netlogic: Mark Netlogic chips as SMT capableHillf Danton1-4/+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.

2011-12-07MIPS: Netlogic: Merge some of XLR/XLP wakup codeJayachandran C10-222/+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.

Use -march=xlr if available, otherwise fallback to mips64. This allows us to support compilation with MIPS toolchains which are not customized for XLR.

2011-09-21MIPS: Do not use EXTRA_CFLAGSArnaud Lacombe1-1/+1
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'.
