63b29d8082 mtd: nand: mxs support oobsize bigger than 512
If ecc chunk data size is 512 and oobsize is bigger than 512, there is
a chance that block_mark_bit_offset conflicts with bch ecc area.

The following graph is modified from kernel gpmi-nand.c driver with
each data block 512 bytes. We can see that Block Mark conflicts with
ecc area from bch view. We can enlarge the ecc chunk size to avoid
this problem to those oobsize which is larger than 512.

7d211fec96 arm: pxa: use common timer functions
This patch moves pxa to the common timer functions added in commit

  8dfafdd - Introduce common timer functions <Rob Herring>

The (removed) pxa timer code (specifically __udelay()) could deadlock at
the 32-bit boundary of get_ticks().  get_ticks() returned a 32-bit value
cast up to a 64-bit value.  If get_ticks() + tmo in __udelay() crossed
the 32-bit boundary, the while condition became unconditionally true and
locked the processor.  Rather than patch the specific pxa issues, simply
move everything over to the common code.

07a8e6d6ee pxa: Fix boot hang by avoiding vector relocation
Since commit 3ff46cc42b ("arm: relocate the exception vectors")
pxa does not boot anymore.

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

This allows pxa to boot again.

cc9429a556 arm: socfpga: Make the pinmux table const u8
Now that we're actually converting the QTS-generated header files,
we can even adjust their data types. A good candidate for this is
the pinmux table, where each entry can have value in the range of
0..3, but each element is declared as unsigned long. By changing
the type to u8, we can save over 600 Bytes from the SPL, so do it.
This patch also constifies the array.

f089240128 arm: socfpga: Split Altera socfpga into AV and CV SoCDK
The board/altera/socfpga directory is not a generic SoCFPGA machine
anymore, but instead it represents the Altera SoCDK board. To make
matters more complicated, it represents both CycloneV and ArriaV
variant.

On the other hand, nowadays, the content of this board directory is
mostly comprised of QTS-generated header files, while all the generic
code is in arch/arm/mach-socfpga already.

Thus, this patch splits the board/altera/socfpga into a separate
board directory for ArriaV SoCDK and CycloneV SoCDK, so that each
can be populated with the correct QTS-generated header files for
that particular board.

cd9b731771 arm: socfpga: Unbind CPU type from board type
The CONFIG_TARGET_SOCFPGA_CYCLONE5 and CONFIG_TARGET_SOCFPGA_ARRIA5
selected both a board and a CPU. This is not correct as these macros
are supposed to select only board.

All would be good, if QTS-generated header files didn't check for
these macros exactly to determine if the platform is Cyclone V or
Arria V. Thus, for the sake of compatibility with not well fleshed
out header file generator, this patch makes these two macros into
a stub config option and introduces new CONFIG_TARGET_SOCFPGA_CYCLONE5_SOCDK
and CONFIG_TARGET_SOCFPGA_ARRIA5_SOCDK targets, which select the
previous stub config option.

The result is that compatibility with QTS is preserved and the new
CONFIG_TARGET_* select actual target boards.

subsequent failure to calibrate DDR when U-Boot was compiled with certain

73a4152b25 mips: Use unsigned int when reading c0 registers
In commit a18a477 (MIPS: use common code from lib/time.c) MIPS platforms
started using common the common timer functions which are based around
the fact that many platforms have a 32-bit free running counter register
that can be used see commit 8dfafdd (Introduce common timer functions).

Even MIPS64 has such a 32-bit register (some have an additional 64-bit free
running counter, but that's something for another time).

The problem is that in __read_32bit_c0_register() we read the value from
this register into an _signed_ int and as it's returned up the call
chain to timer_read_counter() it gets assigned to an unsigned long. On a
32-bit system there is no problem. On a 64-bit system odd things happen,
sign extension seems to kick in and all of a sudden if the counter
register happens to have the MSb (i.e. the sign bit) set the negative
int gets sign extended into a very large unsigned long value. This in
turn throws out things from get_ticks() up.

Update __read_32bit_c0_register() and __read_32bit_c0_ctrl_register() to
use "unsigned int res;" instead of "int res;". There seems to be little
reason to treat these register values as signed. They are either
counters (which by definition are unsigned) or are made up of various
bit fields to be interpreted as per the CPU datasheet.

0f9258228e of: clean up OF_CONTROL ifdef conditionals
We have flipped CONFIG_SPL_DISABLE_OF_CONTROL.  We have cleansing
devices, $(SPL_) and CONFIG_IS_ENABLED(), so we are ready to clear
away the ugly logic in include/fdtdec.h:

 #ifdef CONFIG_OF_CONTROL
 # if defined(CONFIG_SPL_BUILD) && !defined(SPL_OF_CONTROL)
 #  define OF_CONTROL 0
 # else
 #  define OF_CONTROL 1
 # endif
 #else
 # define OF_CONTROL 0
 #endif

Now CONFIG_IS_ENABLED(OF_CONTROL) is the substitute.  It refers to
CONFIG_OF_CONTROL for U-boot proper and CONFIG_SPL_OF_CONTROL for
SPL.

Also, we no longer have to cancel CONFIG_OF_CONTROL in
include/config_uncmd_spl.h and scripts/Makefile.spl.

327f0d23c8 lpc32xx: move common SLC NAND defines to arch/config.h
A number of LPC32xx SLC NAND defines is dictated by controller
hardware limits and OOB layout is defined by operating system, the
definitions are common for all users. Since those macro are used
in out of NAND SLC driver code (simple NAND SPL framework), they can
not be placed into the driver, therefore move them from board config
files to arch/config.h

The change also adds OOB layout details specific to small page NAND

Besides the driver, this patch also removes the statically defined

driver now creates the windows dynamically.

Tested on Armada XP db-mv784mp-gp eval board using an Intel E1000
PCIe card in all 3 PCIe slots. And on the Armada 38x db-88f6820-gp
eval board using this Intel E1000 PCIe card in the PCIe 0 slot.

this already in the bin_hdr (SPL U-Boot). Without this, accessing the

bbc1b99e8b ARM: tegra: represent RAM in 1 or 2 banks
Represent all available RAM in either one or two banks. The first bank
describes any RAM below 4GB. The second bank describes any RAM above 4GB.

This split is driven by the following requirements:
- The NVIDIA L4T kernel requires separate entries in the DT /memory/reg
  property for memory below and above the 4GB boundary. The layout of that
  DT property is directly driven by the entries in the U-Boot bank array.
- On systems with RAM beyond a physical address of 4GB, the potential
  existence of a carve-out at the end of RAM below 4GB can only be
  represented using multiple banks, since usable RAM is not contiguous.

While making this change, add a lot more comments re: how and why RAM is
represented in banks, and implement a few more "semantic" functions that
define (and perhaps later detect at run-time) the size of any carve-out.

way.

query_sdram_size() would previously clip the detected RAM size to at most
just under 4GB in all cases, since on 32-bit systems, larger values could
not be represented. Disable this feature on 64-bit systems since the
representation restriction does not exist.

On 64-bit systems, never call get_ram_size() to validate the detected/
calculated RAM size. On any system with a secure OS/... carve-out, RAM
may not have a single contiguous usable area, and this can confuse
get_ram_size(). Ideally, we'd make this call conditional upon some other
flag that indicates specifically that a carve-out is actually in use. At
present, building for a 64-bit system is the best indication we have of
this fact. In fact, the call to get_ram_size() is not useful by the time
U-Boot runs on any system, since U-Boot (and potentially much other early
boot software) always runs from RAM on Tegra, so any mistakes in memory
controller register programming will already have manifested themselves
and prevented U-Boot from running to this point. In the future, we may
simply delete the call to get_ram_size() in all cases.

5a30cee5d0 tegra: Correct logic for reading pll_misc in clock_start_pll()
The logic for simple PLLs on T124 was broken by this commit:

  722e000c Tegra: PLL: use per-SoC pllinfo table instead of PLL_DIVM/N/P, etc.

Correct it by reading from the same pll_misc register that it writes to and
adding an entry for the DP PLL in the pllinfo table.

35f590f4c3 ARM: tegra: Make pinmux.h standalone includible
This header file uses type definitions (u8, u32) from linux/types.h but
doesn't include it. If includes aren't carefully ordered this can cause
build failures.

29ce99955e apalis/colibri_t30: fix usb dm regression
Unfortunately currently both Apalis T30 as well as Colibri T30 crash
upon starting USB host support. This is due to the following patch not
having taken into account that our T30 device trees were defaulting to
peripheral only mode instead of otg:

commit ddb9a502d1
dm: usb: tegra: Move most of init/uninit into a function

This patch fixes this by defaulting to otg now.

36a01bdd80 apalis/colibri_t20/30: clean-up
Various clean-ups either in comments, order or spacing without any
functional impact:
- Add some comments in the device trees resp. reorder some parameters
  for consistency across all our modules.
- Sort some include files alphabetically (while leaving common.h on
  top of course).
- Streamline some comments in the configuration files and fix the
  spacing from using spaces to tabs.
