ef123c5253 Refactor linker-generated arrays
Refactor linker-generated array code so that symbols
which were previously linker-generated are now compiler-
generated. This causes relocation records of type
R_ARM_ABS32 to become R_ARM_RELATIVE, which makes
code which uses LGA able to run before relocation as
well as after.

Note: this affects more than ARM targets, as linker-
lists span possibly all target architectures, notably
PowerPC.

04380c651a MIPS: add dynamic relocation support
The code handles relocation entries with the
following relocation types only:
  mips32: R_MIPS_REL32
  mips64: R_MIPS_REL+R_MIPS_64
  xburst: R_MIPS_REL32

Other relocation entries are skipped without
processing. The code must be extended if other
relocation types must be supported.

Add -pie to LDFLAGS_FINAL to generate the .rel.dyn
fixup table, which will be applied to the relocated
image before transferring control to it.

The CONFIG_NEEDS_MANUAL_RELOC is not needed
after the patch, so remove that as well.

This section contain the table needed for dynamic

code to access the table.

Discard all sections which are not needed in the final
ELF binary and U-Boot image. Section .dynsym cannot be

6d86227880 MIPS: xburst: simplify relocation offset calculation
The current code uses four instructions and a
temporary register to calculate the relocation
offset and to adjust the gp register.

The relocation offset can be calculated directly
from the CONFIG_SYS_MONITOR_BASE constant and from
the destination address. The resulting offset can
be used to adjust the gp pointer.

This approach makes the code a bit simpler because
it needs two instructions only.

67d80c9f97 MIPS: start.S: don't save flush_cache parameters in advance
Saving the parameters in advance unnecessarily complicates
the code. The destination address is already saved in the
's2' register, and that register is not clobbered by the
copy loop. The size of the copied data can be computed
after the copy loop is done.

Change the code to compute the size parameter right
before calling flush_cache, and set the destination
address parameter in the delay slot of the actuall
call.

f321b0f99f MIPS: start.S: set sp register directly
The current code uses two instructions to load
the stack pointer into the 'sp' register.

This results in the following assembly code:

    468:   3c088040        lui     t0,0x8040
    46c:   251d0000        addiu   sp,t0,0

The first instuction loads the stack pointer into
the 't0' register then the value of the 'sp' register
is computed by adding zero to the value of the 't0'
register. The same issue present on the 64-bit version
as well:

    56c:   3c0c8040        lui     t0,0x8040
    570:   659d0000        daddiu  sp,t0,0

Change the code to load the stack pointer directly
into the 'sp' register. The generated code is functionally
equivalent to the previous version but it is simpler.

  32-bit:
    468:   3c1d8040        lui     sp,0x8040

  64-bit:
    56c:   3c1d8040        lui     sp,0x8040

14fdd1a8bf MIPS: start{, 64}.S: fill branch delay slots with NOP instructions
The romReserved and romExcHandle handlers are
accessed by a branch instruction however the
delay slots of those instructions are not filled.

Because the start.S uses the 'noreorder' directive,
the assembler will not fill the delay slots either,
and leads to the following assembly code:

  0000056c <romReserved>:
   56c:   1000ffff        b       56c <romReserved>

  00000570 <romExcHandle>:
   570:   1000ffff        b       570 <romExcHandle>

In the resulting code, the second branch instruction
is placed into the delay slot of the first branch
instruction, which is not allowed on the MIPS
architecture.

c60795f41d usb: use linux/usb/ch9.h instead of usbdescriptors.h
Linux usb/ch9.h seems to have all the same information (and more)
as usbdescriptors.h so use the former instead of the later one.

As a consequense of this change USB_SPEED_* values don't correspond
directly to EHCI speed encoding anymore, I've added necessary
recoding in EHCI driver. Also there is no point to put speed into
pipe anymore so it's removed and a bunch of host drivers fixed to
look at usb_device->speed instead.

Old usbdescriptors.h included is not removed as it seems to be
used by old USB device code.

This makes usb.h and usbdevice.h incompatible. Fortunately the
only place that tries to include both are the old MUSB code and
it needs usb.h only for USB_DMA_MINALIGN used in aligned attribute
on musb_regs structure but this attribute seems to be unneeded
(old MUSB code doesn't support any DMA at all).

5b84dd67cf usb: replace wait_ms() with mdelay()
Common code has a mdelay() func, so use that instead of the usb-specific
wait_ms() func.  This also fixes the build errors:

c4c9fbebae consolidate mdelay by providing a common function for all users
There are several mdelay() definitions in the driver and
board code. Remove them all and provide a common mdelay()
in lib/time.c.

80421fcc3e MIPS: Ingenic XBurst Jz4740 processor support
Jz4740 is a multimedia application processor targeting for mobile
devices like e-Dictionary, eBook, portable media player (PMP) and
GPS navigator.  Jz4740 is powered by Ingenic 360 MHz XBurst CPU core
(JzRISC), in which RISC/SIMD/DSP hybrid instruction set architecture
provides high integration, high performance and low power consumption.

JzRISC incorporated in Jz4740 is the advanced and power-efficient
32-bit RISC core, compatible with MIPS32, with 16K I-Cache and 16K
D-Cache, and can operate at speeds up to 400 MHz.

On-chip modules such as LCD controller, embedded audio codec, multi-
channel SAR-ADC, AC97/I2S controller and camera I/F offer a rich
suite of peripherals for multimedia application.  NAND controller
(SLC/MLC), USB (host 1.1 and device 2.0), UART, I2C, SPI, etc. are
also available.

For more info about Ingenic XBurst Jz4740:
  http://en.ingenic.cn/eng/
  http://www.linux-mips.org/wiki/Ingenic

This patch introduces XBurst CPU support in U-Boot.  It's compatible
with MIPS32, but requires a bit different cache maintenance, timer
routines, and boot mechanism using USB boot tool, so XBurst support
can go into a separate new home, cpu/xburst/.

dc344589de MIPS: mips32: fix wrong loop bound in flush_cache()
The issue is found when calling flush_cache() with zero "size" argument.
The bound of loop is miscalculated in this case and flush_cache() enters
a wrong flushing loop.

ab2a98b117 MIPS: make cache operation mode configurable
Currently the cache operation mode is hard-coded to
CONF_CM_CACHABLE_NONCOHERENT. This is not appropiate for CPUs or SOCs
which operate at a different mode.

This patch makes the cache operation mode configurable via board config.

7185adb48e MIPS: rename INFINEON_EBU_BOOTCFG to CONFIG_SYS_XWAY_EBU_BOOTFG
This define is a board-specific config option and should be
renamed to follow the U-Boot naming convention. Additionally,
add an explaining comment for this option.
