imx6ul-phytec-phycore-som: don't use fsl, no-blockmark-swap for the NAND ...

barebox doesn't honor that property which yields to inconsitencies
between Linux and barebox after for example filling an UBI with a file
system with barebox and then trying to mount that from Linux.

Note this is an interruptive change as it requires to rewrite the flash
to make it working with Linux again.

images: fix force rebuild of piggy.o ...

piggy.o would be build for every time barebox was built
This had the sideeffect that the image(s) would
always be rebuilt despite no changes

Fix this by adding piggy.o to targets
and avoid an extra command in the rule to create .pblb files

The patch includes the removal of a stray assignment

|    AM3517: Changed default clock rate for AM3517
|
|    Changed #define MPU_M_13_ES2 from 0x1F4 to 0x258, this allows
|    the AM3517 to boot up at 600MHz instead of 500 MHz

ARM: omap3: Add support for reset reason detection ...

Due to the Errata i520, the reset code in the linux kernel aswell in barebox
triggers a cpu reset by setting the bit RST_DPLL3 in the PRM_RSTCTRL register.
This induces a global cold reset on the chip. So we will always detect a POR as
reset source when a reboot of the chip is triggerd. Other states like WDG, JTAG
were tested successfully.

mtd: nand: omap: unbreak BCH8 support ...

We now tell the NAND layer that we have subpages with 512 bytes each.
This means the calculate_ecc / correct hooks are also called for each
subpage which means we cannot iterate over subpages in the calculate_ecc
callback.

Implement this correctly by removing the loop over subpages in the
calculate_ecc callback and by implementing a read_page callback.

With this the bch8_hw and bch8_hw_romcode were tested on AM335x, OMAP4
and AM3517. Number of bitflips is correctly reported as tested with the
nand_bitflip tool.

mtd: nand: omap: fix bch8_hw_romcode ecc layout ...

The ecc layout we provide to the nand core is broken since
00f119a293. Before this commit ecc bytes/size were per page
and now they are per subpage. The offset for the first ecc
byte was calculated as oob_end - num_ecc_bytes which must
now become oob_end - num_ecc_bytes * ecc_steps.
