steven miao 55835175a0 Blackfin: bf54x: add kconfig for UART2/3 DMA channel assignments
The BF54x lacks dedicated DMA channels for the UART peripherals and need
to be muxed between others.  So add a kconfig option so people can select
which channels the UARTs will use so they can pick between SPORTs and the
less commonly used EPPI/PIXC peripherals.

Mike Frysinger 5df326aca4 Blackfin: push BF5Xx configs down into mach-specific Kconfigs
While we're moving the BF54x code, have the BF54xM variants select the
normal BF54x values so that the rest of the Kconfig tree doesn't need to
check the BF54xM variant everytime it wants to check the BF54x.

Graf Yang 1fa9be72b5 Blackfin: add support for gptimer0 as a tick source
For systems where the core cycles are not a usable tick source (like SMP
or cycles gets updated), enable gptimer0 as an alternative.

Sonic Zhang 8d5c2f03bb Blackfin: Allow bf548 ATAPI to be routed to GPIO
By default, it is routed to async memory address. In GPIO case,
GPIO peripheral PINs should be requested in advance.

Yi Li 6a01f23033 Blackfin arch: merge adeos blackfin part to arch/blackfin/
[Mike Frysinger <vapier.adi@gmail.com>:
 - handle bf531/bf532/bf534/bf536 variants in ipipe.h
 - cleanup IPIPE logic for bfin_set_irq_handler()
 - cleanup ipipe asm code a bit and add missing ENDPROC()
 - simplify IPIPE code in trap_c
 - unify some of the IPIPE code and fix style
 - simplify DO_IRQ_L1 handling with ipipe code
 - revert IRQ_SW_INT# addition from ipipe merge
 - remove duplicate get_{c,s}clk() prototypes

Roy Huang 24a07a1241 Blackfin arch: initial supporting for BF548-EZKIT
The ADSP-BF54x was specifically designed to meet the needs of convergent multimedia
applications where system performance and cost are essential ingredients. The
integration of multimedia, human interface, and connectivity peripherals combined
with increased system bandwidth and on-chip memory provides customers a platform to
design the most demanding applications.

Since now, ADSP-BF54x will be supported in the Linux kernel and bunch of related drivers
such as USB OTG, ATAPI, NAND flash controller, LCD framebuffer, sound, touch screen will
be submitted later.

Please enjoy the show.
