Remove fdt_high and initrd_high as they shouldn't be used,

This implies to set CONFIG_SYS_BOOTMAPSZ to indicate the

stm32mp1: remove fdt_high and initrd_high in environment

enviromnent, and U-Boot always relocate FDT and initrd in bootm command.

This relocation is limited by CONFIG_SYS_BOOTMAPSZ which indicates
the size of the memory region where it is safe to place data passed
to the Linux kernel (DTB, initrd), it is
a) Less than or equal to RAM size.
b) not within the kernel's highmem region

So 256M seems large enough in most circumstances and users
can override this value via environment variable "bootm_mapsize"
if needed.

This modification increases the boot time but avoid assumption
on aligned address for bootm command.

A user can still define this variables themselves if the FDT or
initrd is either left in-place or copied to a specific location.

regulator: fix: Move code to enable gpio regulator to pre_probe from ofdata_to_platdata

The commit e8e9715df2d4 ("regulator: fixed: Modify enable-active-high behavior")
fixed the regulator driver behavior when 'enable-active-high' is defined.
Unfortunately, this patch used dm_regulator_platdata()'s "boot_on" member
to set GPIOD_IS_OUT_ACTIVE flag and enable the regulator.

The issue here is that regulator_common_ofdata_to_platdata() is called
_before_ regulator_pre_probe() function in which the 'regulator-boot-on'
property is asserted.

As a result the GPIOD_IS_OUT_ACTIVE flag is not set and gpio_request_by_name()
called in the former function is not enabling the regulator.
This is problematic for e.g. i.MX ethernet driver, which then tries to
perform initialization without power (and fails).

The solution here is to explicitly enable regulator in regulator_pre_probe()
callback only when 'regulator-boot-on' property is present in device tree.
The GPIOD_IS_OUT_ACTIVE flag is not set at all, but relevant gpio is
requested.

4 years agoriscv: Fix breakage caused by linker relaxation
Sean Anderson [Wed, 18 Dec 2019 02:35:32 +0000 (21:35 -0500)]
riscv: Fix breakage caused by linker relaxation

Due to the two-instruction sequence needed to access arbitrary memory
locations, the RISC-V linker aggressively optimises memory accesses and
jumps at link-time. This is called "linker relaxation," and is discussed
in this SiFive article
<https://www.sifive.com/blog/all-aboard-part-3-linker-relaxation-in-riscv-toolchain>.
One of the optimizations in place is to assume that the __global_pointer
symbol is placed in the gp register. To quote the article:

"...The magic __global_pointer$ symbol is defined to point 0x800 bytes
past the start of the .sdata section. The 0x800 magic number allows
signed 12-bit offsets from __global_pointer$ to address symbols at the
start of the .sdata section. The linker assumes that if this symbol is
defined, then the gp register contains that value, which it can then use
to relax accesses to global symbols within that 12-bit range. The
compiler treats the gp register as a constant so it doesn't need to be
saved or restored, which means it is generally only written by _start,
the ELF entry point."

However, U-Boot instead keeps the global data pointer in gp. This causes
memory accesses and jumps optimized to use the gp pointer to fail. To
fix this problem, we undefine the __global_pointer symbol.

cmd: gpio: Correct do_gpio() return value

Use the correct return value in function do_gpio() and update
commands documentation with the return values from command_ret_t enum.

CMD_RET_SUCCESS is returned on command success and CMD_RET_FAILURE is
returned on command failure.

The command was returning the pin value, which caused confusion when
debugging (#define DEBUG).

dm: irq: Add support for requesting interrupts

At present driver model supports the IRQ uclass but there is no way to
request a particular interrupt for a driver.

Add a mechanism, similar to clock and reset, to read the interrupts
required by a device from the device tree and to request those interrupts.

U-Boot itself does not have interrupt-driven handlers, so just provide a
means to read and clear an interrupt. This can be useful to handle
peripherals which must use an interrupt to determine when data is
available, for example.

Bring over the basic binding file as well, from Linux v5.4. Note that the
older binding is not supported in U-Boot; the newer 'special form' must be
used.

Add a simple test of the new functionality.
