Maxime Ripard [Mon, 27 Feb 2017 17:22:09 +0000 (18:22 +0100)]
mtd: sunxi: Change U-Boot offset

The default U-Boot offset for the Allwinner SoCs was set to 32kB.

This was probably to try to maintain some compatibility with the current
image that we build for the MMC where the U-Boot binary is also located at
a 32kB offset.

However, this causes a number of issues. The first one is that it prevents
us from using a backup SPL entirely, which is troublesome in case where the
first would be corrupt (especially on MLC which have a higher number of
bitflips).

We also cannot use the original MMC image on the NAND, because we need to
prepare the SPL image to include the ECCs and randomizer settings, which
reduces the interest of setting it at that particular offset.

It also prevents us from upgrading and flashing the U-Boot and SPLs
independantly, since it's very likely that it will fall in the same erase
block.

Since that default wasn't used by any board, change it for 8MB, which will
be in an erase block of its own, all the erase blocks being multiple of
two. The highest erase block size we encountered is 4MB, which means that
in this particular setup, the first and second erase blocks will be for the
SPL and its backup, and the third for U-Boot.

nand: sunxi: Fix modulo by zero error

When trying to autodetect the ECC and randomization configurations, the

In this case, the number of seeds is obviously 0, and the randomize boolean
is set to false.

However, the logic that retrieves the seed for a given page offset will
blindly use the number of seeds, without testing if the randomization is
enabled, basically doing a modulo by 0.

was our expected value in such a case, and why we would not detect it.
However, U-Boot's libgcc will for some reason return from the function
instead, resulting in an error to load the U-Boot binary in the SPL.

For the RK3399-Q7, we want a default boot-order of SPI -> MMC -> uSD.
This both follows how the BootROM probes devices and is a sane default
for customers in device-personalisation (e.g. it allows for quick and
easy factory programming of unpersonalised devices using an SD card)
and field usage (with customer devices expected to have their firmware
either in SPI or MMC).

However, when probing multiple interfaces (according to the result
from the board_boot_order function), we need to ensure that only valid
FIT images are considered and disable the fallback to assuming that a
raw (binary-only) U-Boot image is loaded (to avoid hangs/crashes from
jumping to random content loaded from devices that are probed, but
don't contain valid image content).

By disabling the SPL_RAW_IMAGE_SUPPORT and SPL_LEGACY_IMAGE_SUPPORT
options, we ensure that raw images (indistinguishable from random
data) are not considered for booting.

RK3288 to switch it to RGMII and set up the TX/RX delays for Gigabit).
The key difference is that the register offsets (within the GRF block)
and bit-offsets (within those registers) used to hold the configuration
differ between the various RK32/33 CPUs.

This change refactors the gmac_rockchip.c driver to use a function
table (selected via driver_data) to factor out these differences. Each
function's implementation then matches the underlying processor.

Some collateral changes are needed in the definitions describing the
bits and offsets in the GRF are needed to prefix each set of symbolic
constants with the SoC name to avoid name clashes... and in doing so,
the shifts for masks and constants have been moved into the header
files for readability (and to make it easier to stay below 80 chars).

rockchip: clk: rk3399: add clocking support for Ethernet

The Ethernet driver for the RK3288/3399 GMAC makes sure that the clock
is ungated through a call to clk_set_rate(...). Even though nothing
needs to be done on the RK3399 (the clock gates are open and the clock
is external), we need to implement enough support to at least return
success to enable driver probing.

rockchip: clk: rk3399: fix warnings for unused variables in SPL/non-SPL

Due to differences in the code paths for SPL and non-SPL, some static
constant structures remain unused in each build variant. This raises
warnings with recent GCC versions (we currently use GCC-6.3).

The warnings addressed in this commit (by matching #if conditions for
the variable definition with their uses) are:

* for the SPL build:
    drivers/clk/rockchip/clk_rk3399.c:53:29: warning: 'cpll_init_cfg' defined but not used [-Wunused-const-variable=]

rockchip: pinctrl: rk3399: add GMAC (RGMII only) support

To add GMAC (Gigabit Ethernet) support (limited to RGMII only at this
point), we need support for additional pin-configuration.  This commit
adds the pinctrl support for GMAC in RGMII signalling mode:
 * adds a PERIPH_ID_GMAC and the mapping from IRQ number to PERIPH_ID
 * adds the required defines (in the GRF support) for configuring the
   GPIOC pins for RGMII
 * configures the RGMII pins (in GPIOC) when requested via pinctrl
