326a682358 malloc_f: enable SYS_MALLOC_F by default if DM is on
This option has a bool type, not hex.
Fix it and enable it if CONFIG_DM is on because Driver Model always
requires malloc memory.  Devices are scanned twice, before/after
relocation.  CONFIG_SYS_MALLOC_F should be enabled to use malloc
memory before relocation.  As it is board-independent, handle it
globally.

97ec89e501 kbuild: remove "*_felconfig" target
This target was added by commit cbdd9a9737 (sunxi: kconfig: Add
%_felconfig rule to enable FEL build of sunxi platforms.).

At that time, U-Boot used separate .config files for U-Boot proper
and SPL.  I understood the pain to modify both .config and
spl/.config.

Now, we have switched to single .config configuration.
It seems acceptable to run "make menuconfig" or friends to enable
CONFIG_SPL_FEL, as we do for other CONFIGs.

99deda1dff sunxi: axp209: fix incorrect limits on ldo3
board/sunxi/board.c tries to set ldo3 to 2.8v however drivers/power/axp209.c
contains an incorrect limit on ldo3 of 2.275v

The origin of the incorrect limit seems likely due to some inconsistencies
in the axp209 datasheet. ldo3 is described with different limits in
different sections. register 0x29 uses 7 bits for voltage configuration
while the 2.275v limit would apply if only 6 bits were used.
Probably this is a cut&paste error from register 0x23

The linux kernel driver has the correct limit and operation up to the 2.8v
required by my board has been physically verified with a multimeter.

a923abc2d3 sunxi: set GMAC TX delay = 0x1 on Cubietruck.
Of 4 boards in our automated test system 2 do not have reliable
networking with the default TX delay of 0x0. Increasing to 0x1 seems
to make things reliable on all 4 boards.

Some previous ad-hpoc tests with tx delay set to 0, 1, 2 and 3 on one
of the problematic boards showed:

0: mw.l 0x1c20164 0x006 1     -- t/o in 4/5 tftp runs
1: mw.l 0x1c20164 0x406 1     -- t/o in 1/5 tftp runs
2: mw.l 0x1c20164 0x806 1     -- t/o in 1/5 tftp runs
3: mw.l 0x1c20164 0xc06 1     -- t/o many times in first tftp run

For 0, 1 and 2 "t/o" means one or two "T" glitches in the download,
but it did complete. For 3 those were basically continuous and it
couldn't complete.

tftp was of a 16M initrd.

CONFIG_SYS_DCACHE_OFF conditional.  The same conditional in the
caller (arch/arm/mach-uniphier/cache_uniphier.c) is redundant.

a509161a21 ARM: UniPhier: disable L2 cache by lowlevel_init of U-Boot proper
The L2 cache is used as a temporary SRAM on SPL.
Now the secondary CPUs store the necessary code for jumping to
Linux on their L1 I-caches.  So, the L2 cache can be disabled
much earlier, at the very entry of U-Boot proper (lowlevel_init).
This makes the boot sequence clearer.
Also, as the L1 cache has been disabled by the start.S,
enable_caches() does not need to do it again.

62118b7b01 ARM: UniPhier: optimize kicking secondary CPUs code
Currently, the secondary CPU(s) are kicked three times:
Boot ROM ---(kick)--> SPL ---(kick)--> U-boot ---(kick)--> Linux.
It makes the boot sequence very complicated.

This commit merges the first and the second kicks, so the secondary
CPU(s) can directly jump from SPL to Linux.
arch/arm/mach-uniphier/smp.S is no longer necessary.

Linux boot test passed.

def3feb8cb ARM: UniPhier: add empty lowlevel_init to U-boot proper
To remove the ifdef conditional of CONFIG_SKIP_LOWLEVEL_INIT,
add late_lowlevel_init.S to U-Boot proper.
