arm: allow the debug stuff in CP14 to be disabled at compile time The upcoming QCA ipq401x support detects the CP14 debug features, but any attempt to use it causes an undefined instruction error. It apparently needs a specific TZ image loaded by the early bootloader (SBL) in order to enable these kinds of features. So add a new kernel option that explicitly disables this in the arm code - the debugger works fine without it.

Remake support for SMP kernel on UP cpu: - Use new option SMP_ON_UP instead of (mis)using specific CPU type. By this, any SMP kernel can be compiled with SMP_ON_UP support. - Enable runtime detection of CPU multiprocessor extensions only if SMP_ON_UP option is used. In other cases (pure SMP or UP), statically compile only required variant. - Don't leak multiprocessor instructions to UP kernel. - Correctly handle data cache write back to point of unification. DCCMVAU is supported on all armv7 cpus. - For SMP_ON_UP kernels, detect proper TTB flags on runtime. Differential Revision: https://reviews.freebsd.org/D9133

FREEBSD_BOOT_LOADER opt_global.h
Allow to override default kernel virtual address assignment on ARM Each plaform performs virtual memory split between kernel and user space and assigns kernel certain amount of memory space. However, is is sometimes reasonable to change the default values. Such situation may happen on systems where the demand for kernel buffers is high, many devices occupying memory etc. This of course comes with the cost of decreasing user space memory range so shall be used with care. Most embedded systems will not suffer from this limtation but rather take advantage of this potential since default behavior is left unchanged.

Add a new ARM kernel option, LOCORE_MAP_MB, to control the size of the kernel VA mapping in the temporary page tables set up by locore-v6.S. The number used to be hard-coded to 64MB, which is still the default if the kernel option is not specified. However, 64MB is insufficient for using a large mdroot filesystem. The hard-coded number can't be safely increased because too large a number may run into memory-mapped IO space on some SoCs that must not be mapped as ordinary memory.

Create a new option ARM_USE_V6_BUSDMA to force an armv4/5 kernel to use the armv6 busdma interface. This interface uses more memory than the armv4 one, but bounces more data more often so may be more correct than the armv4 one. It is intended for debugging purposes only at the moment.

Resurrect Skyeye support : Add a new option, SKYEYE_WORKAROUNDS, which as the name suggests adds workarounds for things skyeye doesn't simulate. Specifically : - Use USART0 instead of DBGU as the console, make it not use DMA, and manually provoke an interrupt when we're done in the transmit function. - Skyeye maintains an internal counter for clock, but apparently there's no way to access it, so hack the timecounter code to return a value which is increased at every clock interrupts. This is gross, but I didn't find a better way to implement timecounters without hacking Skyeye to get the counter value. - Force the write-back of PTEs once we're done writing them, even if they are supposed to be write-through. I don't know why I have to do that.

Port the new PV entry allocator from amd64/i386/mips to armv6/v7. PV entries are now roughly half the size. Instead of using a shared UMA zone for 28 byte pv entries (two 8-byte tailq nodes, a 4 byte pointer, a 4 byte address and 4 byte flags), we allocate a page at a time per process. This provides 252 pv entries per process (actually, per pmap address space) and eliminates one of the 8-byte tailq entries since we now can track per-process pv entries implicitly. The pointer to the pmap can be eliminated by doing address arithmetic to find the metadata on the page headers to find a single pointer shared by all 252 entries. There is an 8-int bitmap for the freelist of those 252 entries. When in serious low memory condition, allocation of another pv_chunk is possible by freeing some pages in pmap_pv_reclaim(). Added pv_entry/pv_chunk related statistics to pmap. pv_entry/pv_chunk statistics can be accessed via sysctl vm.pmap. Ported PTE freelist of KVA allocation and maintenance from i386. Using an idea from Stephan Uphoff, use the empty pte's that correspond to the unused kva in the pv memory block to thread a freelist through. This allows us to free pages that used to be used for pv entry chunks since we can now track holes in the kva memory block. As both ARM pmap.c and pmap-v6.c use the same header and pv_entry, pmap and md_page structures are different, it was needed to separate code designed for ARMv6/7 from the one for other ARMs. Submitted by: Zbigniew Bodek <zbb@semihalf.com> Reviewed by: alc Sponsored by: The FreeBSD Foundation, Semihalf

arm: add SOC_BRCM_BCM2837 option, include it in GENERIC We use armv7/GENERIC for the RPI2 images. The original RPI2 is actually a 32-bit BCM2836, but v1.2 was upgraded to the 64-bit BCM2837. The project continues to provide the RPI2 image as armv7, as it's the lowest common denominator of the two. Historically, we've just kind of implicitly acknowledged this by including some bcm2837 bits on a SOC_BCM2836 kernel config -- this worked until r354875 added code that actually cared. Acknowledge formally that BCM2837 is valid in arm32. This name is inconsistent with the other BCM* SOC on !arm64 for two reasons: 1. It's a pre-existing option on arm64, and 2. the naming convention on arm/ should've arguably changed to include BRCM #1 seems to be a convincing enough argument to maintain the existing name for it.
