4425e62856 arm: socfpga: clock: Drop nonsense inlining from clock manager code
The inlining is done by GCC when needed, there is no need to do it
explicitly. Furthermore, the inline keyword does not force-inline
the code, but is only a hint for the compiler. Scrub this hint.

039b77396a powerpc: add --bss-plt to LDFLAGS
With some versions of gcc (that we know of 4.6.3 and 4.8.2 are affected)
it is necessary to specify --bss-plt to get the final blrl in the

relocated.  For the P2041RDB board this ended up being
NetArpWaitTimerStart which caused the ARP packets to timeout

Every mpc8xx board has its own linker script under the board

At the high level, the problem is that we set gd multiple times (and
still do, even after the commit we're reverting).  We set important
parts of gd to the copy which is not above stack but rather in the data

next release we shall correct things to only, really, set gd once to an
appropriate location and ensure that comments about it are correct too.

a7f99bf139 arm: Fix _start for CONFIG_SYS_DV_NOR_BOOT_CFG
The boards using CONFIG_SYS_DV_NOR_BOOT_CFG (i.e. calimain,
da850evm_direct_nor and enbw_cmc) had the _start symbol defined after
the CONFIG_SYS_DV_NOR_BOOT_CFG word rather than before it in
arch/arm/lib/vectors.S. Because of that, if by lack of luck
'gd->mon_len = (ulong)&__bss_end - (ulong)_start' (see setup_mon_len())
was a multiple of 4 kiB (see reserve_uboot()), then the last BSS word
overlapped the first word of the following reserved RAM area (or went
beyond the top of RAM without such an area) after relocation because
__image_copy_start did not match _start (see relocate_code()).

This was broken by commit 41623c9 'arm: move exception handling out of
start.S files', which defined _start twice (before and after the
CONFIG_SYS_DV_NOR_BOOT_CFG word), then by commit 0a26e1d 'arm: fix a
double-definition error of _start symbol', which kept the definition of
the _start symbol after the CONFIG_SYS_DV_NOR_BOOT_CFG word. This new
commit fixes this issue by restoring the original behavior, i.e. by
defining the _start symbol before the CONFIG_SYS_DV_NOR_BOOT_CFG word.

58f9e1ae63 arm: Make reset position-independent
Some boards, like mx31pdk and tx25, require the beginning of the SPL
code to be position-independent. For these two boards, this is because
they use the i.MX external NAND boot, which starts by executing the
first NAND Flash page from the NFC page buffer. The SPL then needs to
copy itself to its actual link address in order to free the NFC page
buffer and use it to load the non-SPL image from Flash before running
it. This means that the SPL runtime address differs from its link
address between the reset and the initial copy performed by
board_init_f(), so this part of the SPL binary must be
position-independent.

This requirement was broken by commit 41623c9 'arm: move exception
handling out of start.S files', which used an absolute address to branch
to the reset routine. This new commit restores the original behavior,
which just performed a relative branch. This fixes the boot of mx31pdk
and tx25.

2fccd2d96b tegra: Convert tegra GPIO driver to use driver model
This is an implementation of GPIOs for Tegra that uses driver model. It has
been tested on trimslice and also using the new iotrace feature.

The implementation uses a top-level GPIO device (which has no actual GPIOS).
Under this all the banks are created as separate GPIO devices.

The GPIOs are named as per the Tegra datasheet/header files: A0..A7, B0..B7,
..., Z0..Z7, AA0..AA7, etc.

Since driver model is not yet available before relocation, or in SPL, a
special function is provided for seaboard's SPL code.

07ee927d2c arm: mx6: ddr: fix cs0_end calculation
Current way of calculation CS0_END field for MMDCx_MDASP register
is problematic because in most cases the user is forced to define
cs_density in an unnatural way: as value - 2, instead of value.

This breaks the abstraction provided by struct mx6_ddr_sysinfo
because the user is forced to be aware of the way the calculation
is performed.

Refactor the calculation.

08155289a4 arm: mx6: ddr: configure MMDC for slow_pd
According to MX6 TRM, both MMDC and DRAM should be configured to
the same powerdown precharge. Currently, mx6_dram_cfg()
configures MMDC for fast pd (MDPDC[7] = 0), and the DRAM for
'slow exit (DLL off)' (MR0[12] = 0).

Configure MMDC for slow pd.
