commit 6183b29559107650cb38f905e069a93ff9da1d7d upstream
Currently while setting the vsel value for dcdc1 and dcdc2
the driver is wrongly masking the entire 8 bits in the process
clearing PFM (bit7) field as well. Hence describe an appropriate
mask for vsel field and modify only those bits in the vsel
mask.Source: http://www.ti.com/lit/ds/symlink/tps65218.pdf

The layout of the eMMC has been updated in commit 33348a383808

updates the GPT table for android to match this new layout for the
following items:
- xloader,
- u-boot
- the u-boot environment variables
- the DTB (aka os args, aka environment)Signed-off-by: Jean-Jacques Hiblot

Increase PHY autonegoiate time from current 8 seconds
to 16 seconds. On some Ethernet switches, 2 times out
of 100, the Micrel KSZ9031 PHY on AM572x IDK board seems
to take more than 8 seconds to establish link at gigabit
speeds.Since the timeout is only an upper bound on waiting time
it should not affect users who do not face the same
problem.Signed-off-by: Sekhar Nori

At present malloc_base/_limit/_ptr are not initialised in spl_init() when
we call spl_init() in board_init_f(). This is due to a recent change aimed
at avoiding overwriting the malloc area set up on some boards by
spl_relocate_stack_gd().However if CONFIG_SPL_STACK_R_MALLOC_SIMPLE_LEN is not defined, we now
skip setting up the memory area in spl_init() which is obviously wrong.To fix this, add a new function spl_early_init() which can be called in
board_init_f().Fixes: b3d2861e (spl: Remove overwrite of relocated malloc limit)

commit 7a53a1a8115b upstream
The problems with the current DFU layout are:
MMC: The space allocated for u-boot is too small for the latest u-boot
(>750KB). We need to increase it. eMMC uses a much bigger area (2MB).
eMMC: region "u-boot.img.raw" overlaps the environment area and the region
"spl-os-image.raw".
both: region "spl-os-image.raw" is quite small and can't handle android
kernelsFixing this requires growing some regions and moving others.
Care has been taken to leave some room for further growth of
"spl-os-args.raw".
Also the "env" now appears in the dfu so that it's apparent that the
region is not free space that can be used to grow "u-boot.img.raw".
The MLO region is 0x100 sectors wide but the 0x100 are unused in case the
MLO comes too overflow this areas.
The total space allocated for those raw binaries is 16MB, of which 13+MB
are reserved for the kernel image.Signed-off-by: Jean-Jacques Hiblot

As per the datasheet[1] available for DDR2 part on board
the OMAP-L138 LCDK, the tXSNR (exit self refresh to a
non-read command) is 137.5 ns. This corresponds to a
value of 20 to be written to T_XSNR register field of
OMAP-L138's DDR configuration. The DDR2 is at 150 MHz.Fix this. The correct value also appears on the initialization
scripts (called CCS GEL files) available on TI's wiki pages[2][1] http://www.samsung.com/global/business/semiconductor/file/product/ds_k4t1gxx4qf_rev12-0.pdf

Right now the u-boot,dm-pre-reloc flag will make each marked node
always appear in both spl and tpl. But systems needing an additional
tpl might have special constraints for each, like the spl needing to
be very tiny.So introduce two additional flags to mark nodes for only spl or tpl
environments and introduce a function dm_fdt_pre_reloc to automate
the necessary checks in code instances checking for pre-relocation
flags.The behaviour of the original flag stays untouched and still marks
a node for both spl and tpl.Signed-off-by: Heiko Stuebner

commit 5bb7318f9c9fcaa029718149ad061c6031c81022 upstream.
The env command 'args_fit' does not define a root path, this forces us to
embed the rootfs into the FIT image. FIT images do not need to contain a
rootfs, when they do not the kernel will fall-back to the kernel argument
'root', if this is not defined the kernel will not boot. It is safe to
add this as when we do have the rootfs in FIT this argument is ignored.
As 'loadfit' is only called from the MMC boot path, use 'args_mmc' to
correctly populate 'bootargs'.Signed-off-by: Andrew F. Davis

The load address of ramdisk, rdaddr is 0x88080000 and fit_loadaddr
is defined as 0x88000000. This leaves only 512Kbytes for the
fit image. When the FIT images are larger than this, it will
overwite the ramdisk and cause the boot to fail.For eg, The K2 HS fit images are a few MB and end up overwriting
the ramdsk. This patch moves the fit_loadaddr to 0x87000000,
leaving a 16MB window for the fit image. This memory can be
reclaimed once the kernel starts running.Signed-off-by: Madan Srinivas
