On the DRA72x (J6Eco) EVM one PMIC SMPS is powering three SoC
core rails. This concept of using one SMPS to supply multiple
core domains (in various, although limited combinations, per
primary device use case) has now become common and is used by
many customer J6/J6Eco designs; it is supported by a number of
corresponding PMIC OTP versions.
This patch implements correct operation of the core voltages
scaling routine by ensuring that each SMPS that is supplying
more than one domain shall be written only once, and with the
highest voltage of those fused in the SoC (or of those defined
in the corresponding header if fuse read is disabled or fails)
for the power rails belonging to the group.
The patch also replaces some PMIC-related magic numbers with
the appropriate definitions. The default OPP_NOM voltages for
the DRA7xx SoCs are updated as well, per the latest DMs.

2 recent sunxi changes have removed the usage of lowlevel_init by moving some

1) It does not just stop s_init from being called, it also stops
cpu_init_cp15 from getting called, which is undesirable.
2) We want u-boot.bin to be usable standalone, without SPL, some people e.g.
use an upstream u-boot.bin together with Allwinner's boot0 loader. So
u-boot.bin must (re)initialize the gpios, timer, etc.

The current sunxi implementation uses gdata, which is going away. It also
sets up DRAM before board_init_f() in SPL.
There is really no reason to do much in s_init() since board_init_f() is
called immediately afterwards. The only change is that we need our own
implementation of board_init_f() which sets up DRAM before the BSS (which
is in DRAM) is cleared.
The s_init() code runs once for SPL and again for U-Boot proper. We
shouldn't need to init the clock/timer/gpio/i2c init twice, so just have it
in SPL.

Prior to this change we set the gd pointer early so that we can store
data in it. This becomes problematic for DM changes as well as being
odd in general. Re-work the code paths so that we don't need to set the

In order to do this we do need to move certain calls from s_init into
spl_board_init(), mainly preloader_console_init and
save_omap_boot_params.

After reboot, reset or even short power off, DRAM typically retains
the old stale data for some period of time (for this type of memory,
the bits of data are stored in slowly discharging capacitors).
The current sun6i/sun8i DRAM size detection logic, which is
inherited from the Allwinner code, relies on using a large magic
signature with the hope that it is unique enough and unlikely to
ever accidentally match this leftover garbage data in RAM. But
this approach is inherently unsafe, as can be demonstrated using
the following test program:
/***** A testcase for reproducing the problem ******/
void main(int argc, char *argv[])
{
size_t size, i;
uint32_t *buf;
/* Allocate the buffer */
if (argc < 2 || !(size = (size_t)atoi(argv[1]) * 1048576) ||
!(buf = malloc(size))) {
printf("Need buffer size in MiB as a cmdline argument\n");
exit(1);
}
/* Fill it with the Allwinner DRAM "magic" values */
for (i = 0; i < size / 4; i++)
buf[i] = 0xaa55aa55 + ((uintptr_t)&buf[i] / 4) % 64;
/* Try to reboot */
system("reboot");
/* And wait */
for (;;) {}
}
/***************************************************/
If this test program is run on the device (giving it a large
chunk of memory), then the DRAM size detection logic in u-boot
gets confused after reboot and fails to initialize DRAM properly.
A better approach is not to rely on luck and abstain from making
any assumptions about the properties of the leftover garbage
data in RAM. Instead just use a more reliable code for testing
whether two different addresses refer to the same memory location.

The sun8i boot0 code fills the DRAM with a "random" pattern before comparing

Commit 8bc347e2ec "ARM: bootm: Allow booting in secure mode on hyp capable
systems" added the capability to select nonsec vs sec mode boot via an
environment var.
There is a subtle gotcha with this functionality, which is that the PSCI nodes
are still created in the fdt (via armv7_update_dt->fdt_psci) even when booting
in secure mode. Which means that if the kernel is PSCI aware then it will fail
to boot because it will try and do PSCI from secure world, which won't work.
This likely didn't get noticed before because the original purpose was to
support booting the legacy linux-sunxi kernels which don't understand PSCI.
To fix expose boot_nonsec (renaming with armv7_ prefix) outside of bootm.c and
use from the virt-dt code.
As well as avoiding the creation of the PSCI nodes we should also avoid
reserving the secure RAM, so do so.

The bmode command forces the SoC to use a specific boot device
by writing its boot mode into SRC_GPR9, and notifying the SoC of
the change using SRC_GPR10[28] bit: if the bit is on, bootROM
uses the value in SRC_GPR9 instead of SRC_SMBR1 to determine
the boot device.
SPL on the other hand is oblivious to this distinction, so once
the bootROM loads SPL from the device configured in SRC_GPR10,
SPL will attempt to load U-Boot from the device configured in
SRC_SMBR1, which is not updated by the bootROM to the value in
SRC_GPR9.
The result is that the selected boot device is not used across all
the boot stages.
Update spl_boot_device() to look at gpr9 when necessary.
