9a32561446 common/board_f.c: fix compile error when tracing disabled
When CONFIG_TRACE is disabled, linking fails with:

common/built-in.o:(.data.init_sequence_f+0x8): undefined reference to `trace_early_init'

To fix, wrap trace init calls with #ifdef CONFIG_TRACE.

While at it, remove the static inline version of the init call from
trace.h as suggested by Simon Glass, since it doesnt work.

88b326a31e lcd: make lcd_drawchars() independant of lcd_base
lcd_logo() has the following return value:

 #if defined(CONFIG_LCD_LOGO) && !defined(CONFIG_LCD_INFO_BELOW_LOGO)
	return (void *)((ulong)lcd_base + BMP_LOGO_HEIGHT * lcd_line_length);
 #else
	return (void *)lcd_base;
 #endif

This return value gets assigned to lcd_console_address.
lcd_console_address is not assigned or modified anywhere else.
Thus:

 #if defined(CONFIG_LCD_LOGO) && !defined(CONFIG_LCD_INFO_BELOW_LOGO):
	y' = BMP_LOGO_HEIGHT + y;
	lcd_base + y' * lcd_line_length ==
	lcd_base + (BMP_LOGO_HEIGHT + y) * lcd_line_length ==
	lcd_base + BMP_LOGO_HEIGHT * lcd_line_length + y * lcd_line_length ==
	lcd_console_address + y * lcd_line_length
 #else
	lcd_base + y * lcd_line_length == lcd_console_address + y * lcd_line_length
 #endif

This is a preparatory step for extracting lcd console code into its own

4c8c485ad9 arc: introduce "mdbtrick" target
MetaWare debugger (MDB) is still used as a primary tool for interaction
with target via JTAG. Moreover some very advanced features are not yet
implemented in GDB for ARC (and not sure if they will be implemnted
sometime soon given complexity and rare need for those features for
common user).

So if we're talking about development process when U-Boot is loaded in
target memory not by low-level boot-loader but manually through JTAG
chances are high developer uses MDB for it.

But MDB doesn't support PIE (position-independent executable) - it will
refuse to even start - that means no chance to load elf contents on
target.
Then the only way to load U-Boot in MDB is to fake it by:
  1. Reset PIE flag in ELF header
     This is simpe - on attempt to open elf MDB checks header and if it
doesn't match its expectation refuces to use provided elf.
  2. Strip all debug information from elf
     If (1) is done then MDB will open elf but on parsing of elf's debug
info it will refuse to process due to debug info it cannot understand
(symbols with PIE relocation).

Even though it could be done manually (I got it documented quite a while
ago here http://www.denx.de/wiki/U-Boot/ARCNotes) having this automated
way is very convenient. User may build U-Boot that will be loaded on
target via MDB saying "make mdbtrick".

Then if we now apply the manipulation MDB will happily start and will
load all required sections into the target.

Indeed there will be no source-level debug info available. But still MDB
will do its work on showing disassembly, global symbols, registers,
accessing low-level debug facilities etc.

As a summary - this is a pretty dirty hack but it simplifies life a lot
for us ARc developers.

ab37b76d5d mtd: nand: do not scan BBT after scrub
Currently, "nand scrub" runs chip->scan_bbt at the end of
nand_erase_opts() even if NAND_SKIP_BBTSCAN flag is set.

It violates the intention of NAND_SKIP_BBTSCAN.

Move NAND_SKIP_BBTSCAN flag check to nand_block_checkbad() so that
chip->scan_bbt() is never run if NAND_SKIP_BBTSCAN is set.

Also, unset NAND_BBT_SCANNED flag instead of running chip->scan_bbt()
right after scrub.  We can be lazier here because the BBT is scanned
at the next call of nand_block_checkbad().

bf80ee6e1d mtd: nand: Mark the BBT as scanned prior to calling scan_bbt again
Commit 35c204d8a9 (nand: reinstate lazy bad block scanning)
broke NAND_BBT_USE_FLASH feature.

Its git-log claimed that it reinstated the change as by commit
fb49454b1b ("nand: reinstate lazy bad block scanning"), but it moved
"chip->options |= NAND_BBT_SCANNED" below "chip->scan_bbt(mtd);".

It causes recursion if scan_bbt does not find a flash based BBT
and tries to write one, and the attempt to erase the BBT area
causes a bad block check.

Reinstate commit ff49ea8977 (NAND: Mark the BBT as scanned prior to
calling scan_bbt.).

b188067f39 arm: vf610: fix boot from SD-card
Boot from SD-card (and probably also from NAND) was broken since
commit d6d07a9bec ("arm: vf610: add NAND support for vf610twr").
It looks like the increased size of U-Boot lead to a situation
where the boot ROM overwrote its own stack/heap while loading
U-Boot from the SD-card to the SRAM. However, U-Boot worked fine
when loaded through USB serial loader directly into SRAM. It
looks like loading from SD-card uses other stack/heap location
then the serial loader (or maybe no stack or heap at all).
This fix moves U-Boot to gfxRAM, which is 512kB in size and is not
used by the boot ROM nor the SD-card loader of it.

75d7a0d7f1 arm: build arch memset/memcpy in Thumb2 mode
Resynchronize memcpy/memset with kernel 3.17 and build them in
Thumb2 mode (unified syntax). Those assembler files can be built
and linked in ARM mode too, however when calling them from Thumb2
built code, the stack got corrupted and the copy did not succeed
(the exact details have not been traced back). However, the Linux
kernel builds those files in Thumb2 mode. Hence U-Boot should
build them in Thumb2 mode too when CONFIG_SYS_THUMB_BUILD is set.

To build the files without warning, some assembler instructions
had to be replaced with their UAL compliant variant (thanks
Jeroen for this input).

To build the file in Thumb2 mode the implicit-it=always option need
to be set to generate Thumb2 compliant IT instructions where needed.
We add this option to the general AFLAGS when building for Thumb2.

906d6fe303 mx25: Fix boot hang by avoiding vector relocation
Since commit 3ff46cc42b ("arm: relocate the exception vectors") mx25pdk

CPU:   Freescale i.MX25 rev1.2 at 399 MHz
Reset cause: WDOG
Board: MX25PDK
I2C:   ready
DRAM:  64 MiB
(hangs)

Add a specific relocate_vectors macro that skips the vector relocation, as the
i.MX25 SoC does not provide RAM at the high vectors address (0xFFFF0000), and
(0x00000000) maps to ROM.

This allows mx25 to boot again.

adc0fabfd9 imx:mx6sxsabresd support qspi AHB read
Add CONFIG_SYS_FSL_QSPI_AHB in header file to enable AHB in driver.
In order to count the time, add CONFIG_CMD_TIME.

Using AHB read can improve the the read speed about 30%.

AHB read:
=> time sf read 0x8f800000 0 100000
SF: 1048576 bytes @ 0x0 Read: OK
time: 0.174 seconds

=> time sf read 0x8f800000 1000000 100000
SF: 1048576 bytes @ 0x1000000 Read: OK
time: 0.174 seconds

IP read:
=> time sf read 0x8f800000 0 100000
SF: 1048576 bytes @ 0x0 Read: OK
time: 0.227 seconds

=> time sf read 0x8f800000 1000000 100000
SF: 1048576 bytes @ 0x1000000 Read: OK
time: 0.227 seconds

Note:
Quad read is not supported in driver, now. In my side, using AHB and Quad read
can achieve about 16MB/s. Anyway, I have plan to reimplement the driver using
DTB and DM, then make the code cleaner and more feature can be added.

5f7f70c171 qspi:fsl implement AHB read
The QSPI controller in i.MX 6SoloX and Vybrid supports reading data using
IP register and AHB bus.

The original driver only supports reading data from IP interface. The IC
team suggests to use AHB read which is faster then IP read. Using AHB read,
we can directly memcpy, a "missed" access to the buffer will cause the
controller to clear the buffer and use the SEQID stored in bfgencr register
to initiate a read from flash device.

Since AHB bus is 64 bit width, we can not set MCR register using 32bit. In
order to minimize code change, redefine QSPI_MCR_END_CFD_LE to 64bit Little
endian but not 32bit Little endia.

Introduce a new configuration option CONFIG_SYS_FSL_QSPI_AHB. If want to
use AHB read, just define CONFIG_SYS_FSL_QSPI_AHB. If not, just ignore it.
Actually if Vybrid is migrated to use AHB read, this option can be removed and
IP read function can be discared. The reason to introduce this option
is that only i.MX SOC is tested in my side, no Vybrid platform for me.

In spi_setup_slave, the original piece code to set AHB is deleted, since
Vybrid platform does not use this to intiate AHB read. Instead, add
qspi_init_ahb_read function if defined CONFIG_SYS_FSL_QSPI_AHB.

b4ad44baab ARM: UniPhier: add UART initialization routine for low-level debug
The low-level debugging functions are useful to debug the early boot
stage where the full UART driver is not available.

UniPhier SoCs need to initialize the UART port 0 to use this feature.
The initialization routine is called at the very entry of the
lowlevel_init().

2661dfd004 ARM: UniPhier: enable output of system bus
For NAND boot on PH1-LD4, PH1-sLD8, and some other SoCs,
the output of the system bus is disabled by default.
It must be enabled by software to have access to the system bus.

5e165b258f ARM: UniPhier: fix SRAM size on support card
The max size of available memories on slot0 and slot1 is 32MB because
 - EA[25] signal is not output on the save-pin mode which is
   used PH1-LD4 or later SoCs.
 - EA[25] signal is not connected by the limitation (or bug?) of
   the PLD logic of DCC support card.

d87cbeccc5 mx6sxsabresd: support qspi flash bigger than 16MB
mx6sxsabresd revb board uses 32MB qspi flash, reva board uses 16MB qspi
flash. Currently, the default supported platform is revb board.

If want to configure for reva board, just define CONFIG_MX6SX_SABRESD_REVA
in mx6sxsabresd.h to support reva qspi flashes whose size is 16MB.

a235878387 spi:fsl-quadspi support bank register read write
To support bigger than 16MB size qspi flashes, spi framework uses bank
switch to access higher bank or lower bank.

In this patch, QSPI_CMD_BRRD, QSPI_CMD_BRWR, QSPI_CMD_WREAR, QSPI_CMD_RDEAR
is initialized in LUT register with related pad and length configuration.
qspi_op_pp is originally for page programming, this patch reuses this function
for bank register switch and renamed it with qspi_op_write.

Since bank or EAR register is only 1 byte length, however original qspi_op_pp
or now renamed qspi_op_write only support 4 bytes lenght as the access unit,
this will trigger data abort exception when access EAR or bank register.
This is because upper framework passes a 1 bytes pointer to qspi_op_write,
however qspi_op_write treat it as an int pointer. This patch fixes this for
accessing EAR or bank register.
