Add .arch_extension sec to fix build. (v7a on it's own complains)
More clock fixes, debugging.
use rockchip_a9periph_get_rate for a9tmr frequency
Preliminary support for P1023.
fenv(3) support for hppa
restrict DMA buffers to the lower 256MB -> now dwc2 DMA works
Fix consistent typo: it is FE_ALL_EXCEPT instead of FE_EXCEPT_ALL (this
went unnoticed as the undefined macro evaluated to 0 and the expression
was always used with ~)
Add our common non standard extensions and fix typo (FE_EXCEPT_ALL ->
FE_ALL_EXCEPT).
Enable fenv.h on arm again
Added SPI register definitions.
Enable fenv for arm
Move the list of <fenv.h> supporting architectures to the makefile and
sync it with other copies.
mmc0 on rk3188 is based on ahb clk, not gpll. add a function to control mmc0 clock as well.
update some bits for rk3188
- Explicitly initialize CLKSRC register.
- Reset FIFO and DMA along with controller.
- Support chips with inverted PWREN logic.
- Enable RXDR and TXDR irqs.
- Set max clk based on supplied clock freq.
- Use external clk control as well as internal divisor to set clock rates.
  Requires bus glue to implement sc_set_clkdiv callback.
set DWC_MMC_F_PWREN_CLEAR, implement set_clkdiv callback; now this works
Cleanup:
 - remove struct kmembuckets (dead)
 - correctly deadify MALLOC_XX
 - remove MALLOC_DEFINE_LIMIT and MALLOC_JUSTDEFINE_LIMIT (dead)
 - remove malloc_roundup(), malloc_type_setlimit(), MALLOC_DEFINE_LIMIT()
   and MALLOC_JUSTDEFINE_LIMIT() from man 9 malloc
Bring this closer to Allwinner / RPI configs:
Add MSDOSFS, KERNFS, PROCFS, INET6, SYSVMSG, SYSVSEM, SYSVSHM, BUFQ_PRIOCSCAN.
Remove DEBUG, LOCKDEBUG, VERBOSE_INIT_ARM.
Change DDB_ONPANIC from 2 to 1.
Cinclude ROCKCHIP.local
New sentence, new line. Bump date for previous.
add DDR offsets
