Merge tag 'arc-for-2019.10-rc4' of https://gitlab.denx.de/u-boot/custodians/u-boot-arc

These are some very late changes mostly required to get 64-bit
division working on ARC boards.

For that we had to import missing parts of libgcc and add compiler
flags to EMSDP which otherwise used very simple profile for compliation.

And while at it another fix for EM SDP initialization is inluded as well.

arc: emsdp: Add more platform-specific compiler options

Even though EM SDP is FPGA-based board and different FPGA
images (known as .bit-files) are awailable for the board still
there's a common subset of options we may rely on for all configs.

These are:
 * Normalizer
 * Swap instructions
 * Simple multiplier
 * Barrel-shifter
 * Floating-point unit
 * Shorter instructions (code density)

This among other improvements allows to compile code with
64-bit divisions, see [1].

code due to missing definition of __udivdi3().

mmc: invalidate block cache after hwpart switched successfully

eMMC device has multiple hw partitions both address from zero. However the
mmc driver lacks block cache invalidation for switch hwpart. This causes a
problem that data of current hw partition is cached before switching to
another hw partition. And the following read operation of the latter hw
partition will get wrong data when reading from the addresses that have
been cached previously.

To solve this problem, invalidate block cache after a successful
mmc_switch_part() operation.

Revert "blk: Invalidate block cache when switching hwpart"

This reverts commit 0ebe112d09b48230ba4be833cd3504b06997d9a4.

Most block devices have only one hwpart. Multiple hwparts only found used
by eMMC devices in u-boot. The mmc driver do blk_dselect_hwpart() at the
beginning of mmc_bread() which causes block cache being invalidated too
frequently and makes block cache useless.

So it's not a good idea to put blkcache_invalidate() in the common
functions. It should be called inside mmc_select_hwpart().

board_f: fix noncached reservation calculation

The current code in reserve_noncached() has two issues:

1) The first update of gd->start_addr_sp always rounds down to a section
start. However, the equivalent calculation in cache.c:noncached_init()
always first rounds up to a section start, then subtracts a section size.
These two calculations differ if the initial value is already rounded to
section alignment.

2) The second update of gd->start_addr_sp subtracts exactly
CONFIG_SYS_NONCACHED_MEMORY, whereas the equivalent calculation in
cache.c:noncached_init() rounds the noncached size up to section
alignment before subtracting it. The two calculations differ if the
noncached region size is not a multiple of the MMU section size.

In practice, one/both of those issues causes a practical problem on
Jetson TX1; U-Boot triggers a synchronous abort during initialization,
likely due to overlapping use of some memory region.

This change fixes both these issues by duplicating the exact calculations
from noncached_init() into reserve_noncached().

However, this fix assumes that gd->start_addr_sp on entry to
reserve_noncached() exactly matches mem_malloc_start on entry to
noncached_init(). I haven't traced the code to see whether it absolutely
guarantees this in all (or indeed any!) cases. Consequently, I added some
comments in the hope that this condition will continue to be true.
