The boot parameters are read from individual variables
assigned for each of them. This been corrected and now
they are stored as a part of the global data 'gd'
structure. So read them from 'gd' instead.

As part of a review of a recent patch to add a new AM335x board, Tom
found several duplicate and/or unused #defines.

This patch simply removes them.

The two affected configs have been recompiled to check nothing was
broken (from a compilation point of view !!)

On TI AM335x devices, MUSB has bulk split/combine feature enabled
in the ConfigData register, but the current MUSB driver does not
support it yet. Therefore, disable the feature for now, until the
driver adds the support.

One usecase which is broken because of this feature is that Ether
gadget stops working in Fullspeed mode (by un-defining
CONFIG_USB_GADGET_DUALSPEED)

After desabled this feature, MUSB driver send packets in proper size
(no more than 64 bytes) in Fullspeed mode.

This has been validated with Ether gadget in Fullspeed mode on AM335x
EVM.

Because of our support for network-based SPL, we don't discard all of
the environment related functions.  We however never make use of the

brings us closer to (or with some toolchains, over) our SPL size limit.

This adds necessary config options and a new build target,
am335x_evm_usbspl, to enable usb booting and fixes board_eth_init()
function to take into account that we may have USB ether support in SPL
now.  This uses the same MAC for both cpsw and USB, in order to match
ROM behavior.

The usbspl build target does not contain UART SPL, CPSW SPL or extra
environment settings, so that we may fit within our binary size
constraint.

For AM335X boards, such as the EVM and Bone Linux kernel fails to
locate the device tree blob on boot. The reason being is that
u-boot is copying the DT blob to the upper part of RAM when booting
the kernel and the kernel is unable to access the blob.
By setting the fdt_high variable to 0xffffffff (to prevent the copy)
the kernel is able to locate the DT blob and boot.

This patch is tested on BeagleBone platform.

Add a new flag, CONFIG_SPL_FRAMEWORK to opt into the common/spl SPL
framework, enable on all of the previously using boards.  We move the
spl_ymodem.c portion to common/ and spl_mmc.c to drivers/mmc/.  We leave
the NAND one in-place as we plan to replace it later in this series.

We use common/spl to avoid linker problems with respect to merging
constant strings in objects.   Otherwise all strings in common/ will be
linked in and kept which grows SPL in size too much.

Make the lowlevel_init function that these platforms have which just
sets up the stack and calls a C function available to all armv7
platforms.  As part of this we change some of the macros that are used
to be more clear.  Previously (except for am335x evm) we had been
setting CONFIG_SYS_INIT_SP_ADDR to a series of new defines that are
equivalent to simply referencing NON_SECURE_SRAM_END.  On am335x evm we
should have been doing this initially and do now.
