ec75fab302 build: Drop CONFIG_SPL_BUILD guards in some cases
Given gcc-6.1 and later we can now safely have strings discarded when
the functions are unused.  This lets us drop certain cases of not
building something so that we don't have the strings brought in when the
code was discarded.  Simplify the code now by dropping guards we don't
need now.

225bfd3906 arch/arm/cpu/arm926ejs/spear/cpu.c: guard do_switch_ecc() with CONFIG_NAND_FSMC
do_switch_ecc() calls fsmc_nand_switch_ecc(), which is a direct
function call into drivers/mtd/nand/fsmc_nand.c. However, this
function is not guarded by CONFIG_NAND_FSMC, which results to a build
failure if CONFIG_NAND_FSMC is disabled.

c25c4fd010 board/spear/common: move code to arch/arm/cpu/arm926ejs/spear/
The code in board/spear/common/ is not board-specific but
SoC-specific. Therefore, boards from other vendors than "spear" may
want to re-use this code, which is currently difficult with the code
being placed in board/spear/common/.

Since this code really is SoC-specific, this commit moves it to
arch/arm/cpu/arm926ejs/spear/, with the rest of the SPEAr related
code.

Change is consistent with other SOCs and it is in preparation

Today, we have cases where we wish to build all of U-Boot in Thumb2 mode for
various reasons.  We also have cases where we only build SPL in Thumb2 mode due

in this migration we introduce a new symbol as well, SPL_SYS_THUMB_BUILD to
control if we build everything or just SPL (or in theory, just U-Boot) in
Thumb2 mode.

17fa032671 serial, ns16550: bugfix: ns16550 fifo not enabled
commit: 65f83802b7 "serial: 16550: Add getfcr accessor"
breaks u-boot commandline working with long commands
sending to the board.

Since the above patch, you have to setup the fcr register.

For board/archs which enable OF_PLATDATA, the new field
fcr in struct ns16550_platdata is not filled with a
default value ...

This leads in not setting up the uarts fifo, which ends
in problems, when you send long commands to u-boots
commandline.

Detected this issue with automated tbot tests on am335x
based shc board.

The error does not popup, if you type commands. You need
to copy&paste a long command to u-boots commandshell
(or send a long command with tbot)

Possible boards/plattforms with problems:
./arch/arm/cpu/arm926ejs/lpc32xx/devices.c
./arch/arm/mach-tegra/board.c
./board/overo/overo.c

067716bac5 ARM: Move SYS_CACHELINE_SIZE over to Kconfig
This series moves the CONFIG_SYS_CACHELINE_SIZE.  First, in nearly all
cases we are mirroring the values used by the Linux Kernel here.  Also,
so long as (and in this case, it is true) we implement flushes in hunks
that are no larger than the smallest implementation (and given that we
mirror the Linux Kernel, again we are fine) it is OK to align higher.
The biggest changes here are that we always use 64 bytes for CPU_V7 even
if for example the underlying core is only 32 bytes (this mirrors
Linux).  Second, we say ARM64 uses 64 bytes not 128 (as found in the
Linux Kernel) as we do not need multi-platform support (to this degree)
and only the Cavium ThunderX 88xx series has a use for such large
alignment.

this should also help 'future-proof' in the event the structure changes.

board.  Appologies if I missed one or stepped on toes.  Thanks to Derald Woods

1222305b55 arm: lpc32xx: switch SPL builds to driver model
For NXP LPC32xx boards the change enables SPL_DM option, this allows
to use any driver model UART driver in SPL images, hence a restriction
on HSUART in SPL image is removed and well as definitions for non-DM
NS16550 driver, its DM version is used instead.

Because SPL_DM requires malloc(), enable CONFIG_SPL_SYS_MALLOC_SIMPLE
for LPC32xx boards.

The change adds about 5KB to the resulting SPL image (for devkit3250
board SPL image is increased from 10672 to 15608 bytes).

fe21eaf92d ARM: mxs: allow boards to select DC-DC switching clock source
For some board designs, it might be useful to switch the DC-DC
clock source to something else rather the default 24 MHz, e.g.
for EMI reasons.

For this, override the mxs_power_setup_dcdc_clocksource function
in your board support files.

Example:
void mxs_power_setup_dcdc_clocksource(void)
{
    mxs_power_switch_dcdc_clocksource(POWER_MISC_FREQSEL_20MHZ);
}

a6b1e25fc6 ARM: mxs: fix VDDD brownout setting
At the moment, the desired brownout is at 1.0V. However,
this setting cannot be realized by hardware since we have
only 3 bits to represent the voltage difference from the
target value.

Target value is 1500 mV, brownout target is 1000 mV,
voltage steps are 25 mV.

Register content calculation:
  (1500 [mV] - 1000 [mV]) / 25 [mV] = 20 (decimal) = 0x14

  Register takes only 3 bits, that is 0x4.

But 0x4 * 25 [mV] = 100 [mV], that means that actual
brownout level is 1500 [mV] - 100 [mV] = 1.4 V.

Minimum possible BO level is
  1500 [mV] - 0x7 * 25 [mV] = 1315 [mV].

So lets use this value as desired BO value (which is
also the same as FSL bootlets use).

633b6ccedf ARM: cache: implement a default weak flush_cache() function
Current many cpu use the same flush_cache() function, which just call
the flush_dcache_range().
So implement a weak flush_cache() for all the cpus to use.

In original weak flush_cache() in arch/arm/lib/cache.c, there has some
code for ARM1136 & ARM926ejs. But in the arch/arm/cpu/arm1136/cpu.c and
arch/arm/cpu/arm926ejs/cache.c, there implements a real flush_cache()
function as well. That means the original code for ARM1136 & ARM926ejs
in weak flush_cache() of arch/arm/lib/cache.c is totally useless.

So in this patch remove such code in flush_cache() and only call
flush_dcache_range().

to deal with a phy connected by RMII.

It's worth to mention that the kernel and legacy BSP from NXP sets
SUPP_RESET_RMII == (1 << 11) bit, however the description of this bit is
missing in shared LPC32x0 User Manual UM10326 Rev. 3, July 22, 2011
and in LPC32x0 Draft User Mannual Rev. 00.27, November 20, 2008, also
in my tests an SMSC LAN8700 phy device connected over RMII seems to
work correctly without touching this bit.

Add support of RMII, if CONFIG_RMII is defined, this option is aligned
with a number of boards, which already define the same config value.

32f9ef3e2b ARM: mxs: Get boot mode from OCRAM
Reading the boot mode pins after power-up does not necessarily represent the
boot mode used by the ROM loader. For example the state of a pin may have
changed because a recovery switch which was pressed to enter USB mode is
already released after plugging in USB.

The ROM loader stores the value a fixed address in OCRAM. Use this value
instead of reading the boot map pins.

The GLOBAL_BOOT_MODE_ADDR for i.MX28 is taken from an U-Boot patch for the
MX28EVK:
http://repository.timesys.com/buildsources/u/u-boot/u-boot-2009.08/u-boot-2009.08-mx28-201012211513.patch

Leave the boot mode detection for the i.MX23 untouched. Someone has to test
whether the i.MX ROM loader does also store the boot mode in OCRAM and if the
address match.

This patch superseeds my incorrect patch:

79d75d7527 ARM: move -march=* and -mtune= options to arch/arm/Makefile
My main motivations for this commit are:

[1] Follow the arch/arm/Makefile style of Linux Kernel

[2] Maintain compiler options systematically
  Currently, we give -march=* and -mtune=* options inconsistently:
  Only some of the CPUs pass -march=* and -mtune=* options.
  By collecting such options into the single place arch/arm/Makefile
  we can tell which options are missing at a glance.

[3] Prepare for deprecating arch/*/cpu/*/config.mk

Note:
  This commit just moves the compiler options so as not to change
  the behavior at all.  It does not care about the correctness of
  the given options.  Fox example, "-march=armv5te" might be better
  than "-march=armv4" for ARM946EJS, but it is beyond the scope this
  commit.  Also, filling the missing -march=* and -tune=* is left
  to follow-up patches.

2d6286ab79 arm: mxs: Add 'Wait for JTAG user' if booted in JTAG mode
When booting in JTAG mode, there is no way to use soft break-points, and
no way of knowing when SPL has finished executing (so the user can issue
a 'halt' command to load u-boot.bin for example)

Add a debug output and simple loop to stop execution at the completion of
the SPL initialisation as a pseudo break-point when booting in JTAG mode

7a08603707 arm: mxs: Enable booting of mx28 without battery
Section 4.1.2 of Freescale Application Note AN4199 describes the
configuration required to operate the mx28 from a 5V source without a
battery.

This patch changes the behaviour of the dropout control of the DC-DC
converter (refer to section 11.12.9 of the mx28 Application Processor
Reference Manual - Document Number: MCIMX28RM, Rev 2, 08/2013) to the
following:
 - Always use 4P2 Linear Regulator if CONFIG_SYS_MXS_VDD5V_ONLY is defined
 - Switch between 4P2 Linear Regulator and Battery, using whichever has
   the highest voltage if CONFIG_SYS_MXS_VDD5V_ONLY isnot set (this is
   the same as the pre-patch behaviour)

950eaf6230 arm: mxs: Add debug outputs and comments to mxs SPL source files
It is difficult to track down fail to boot issues in the mxs SPL.
Implement the following to make it easier:
 - Add debug outputs to allow tracing of SPL progress in order to track
where failure to boot occurs. DEUBUG and CONFIG_SPL_SERIAL_SUPPORT must
be defined to enable debug output in SPL
 - Add TODO comments where it is not clear if the code is doing what it
is meant to be doing, even tough the board boots properly (these comments
refer to existing code, not to any code added by this patch)

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

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.

The Linux-compatible macro DIV_ROUND_CLOSEST is a bit more flexible
and safer than DIV_ROUND.

For example,
  foo = DIV_ROUND_CLOSEST(x, y++)
works expectedly, but
  foo = DIV_ROUND(x, y++)
does not. (y is incremented twice.)

db544b9662 imx: fix exception vectors relocation in imx27
Commit 3ff46cc4 fixed exception vectors setting in
the general ARM case, by either copying the exception
and indirect vector tables to normal (0x00000000) or
high (0xFFFF0000) vectors address, or setting VBAR to
U-Boot's base if applicable.

i.MX27 SoC is ARM926E-JS, thus has only normal and
high options, but does not provide RAM at 0xFFFF0000
and has only ROM at 0x00000000; it is therefore not
possible to move or change its exception vectors.

Besides, i.MX27 ROM code does provide an indirect
vectors table but at a non-standard address and with
the reset and reserved vectors missing.

Turn the current vector relocation code into a weak
routine called after relocate_code from crt0, and add
strong version for i.MX27.

Also, it adds the CPU feature Kconfig symbol HAS_VBAR which is selected
for CPU_ARM1176 and CPU_V7.

For each target, the corresponding CPU is selected and the definition of
SYS_CPU in the corresponding Kconfig file is removed.

Also, it removes redundant "string" type in some Kconfig files.
