Some refactoring of the top-level Kconfig file which includes:
* using "if" to remove numerous identical dependency tests
* reordering config entries to group related ones
* spelling and grammar fixesThere should be no functional changes, only aesthetic ones.

When using ARMv8 with ARMV8_SPIN_TABLE=y, we want the slave cores to
wait on spin_table_cpu_release_addr, until the Linux kernel will "wake" them
by writing to that location. The address of spin_table_cpu_release_addr is
transferred to the kernel using the device tree that is updated by
spin_table_update_dt().However, if we also use SPL, then the slave cores are stuck at
CPU_RELEASE_ADDR instead and as a result, never wake up.This patch releases the slave cores by writing spl_image->entry_point to
CPU_RELEASE_ADDR location before the end of the SPL code
(at jump_to_image_no_args()).That way, the slave cores will start to execute the u-boot and will get to
the spin-table code and wait on the correct address
(spin_table_cpu_release_addr).Signed-off-by: Oded Gabbay

It is not safe to compare timer values directly.
On 32-bit systems, for example, timer_get_us() wraps around every
72 min. (2 ^ 32 / 1000000 =~ 4295 sec =~ 72 min). Depending on
the get_ticks() implementation, it may wrap more frequently.
The 72 min might be possible on the use of U-Boot.Let's borrow time_after, time_before, and friends to solve the
wrap-around problem.These macros were copied from include/linux/jiffies.h of Linux 4.9.

The include/common.h is a collection of unrelated declarations,
macros, etc.It is horrible to include such a cluttered header just for some
timer functions. Split out timer functions into include/time.h.Signed-off-by: Masahiro Yamada

Currently, mdelay() and udelay() are declared in include/common.h,
while ndelay() in include/linux/compat.h. It would be nice to
collect them into include/linux/delay.h like Linux.While we are here, fix the ndelay() implementation; I used the
DIV_ROUND_UP() instead of (x)/1000 because it must wait *longer*
than the given period of time.Signed-off-by: Masahiro Yamada

Using CONFIG_IS_ENABLED() doesn't work in SPL. This patch replaces the only
occurrence of CONFIG_IS_ENABLED() in start.S to a regular #if defined().
It also adds "&& !defined(CONFIG_SPL_BUILD)" to that #if statement because
the spin-table code can't currently work in SPL, and the spin-table file
isn't even compiled in SPL.Signed-off-by: Oded Gabbay

Since commit aa6ab905b2, sata_initialize returns -1 if init_sata or
scan_sata fails. But this return value becomes the do_sata return
value which is equivalent to CMD_RET_USAGE.In case one issues 'sata init' and that the hardware fails to
initialize, there's no need to display the command usage. Instead
the command shoud just return the CMD_RET_FAILURE value.Fixes: aa6ab905b2 (sata: fix sata command can not being executed bug)

This re-syncs the MACH_TYPE_xxx values from the Linux Kernel v4.9
release. In addition this removes all of the machine_arch_type and

On a Raspberry Pi 2 disagreements on cell endianness can be observed:
U-Boot> fdt print /soc/gpio@7e200000 phandle
phandle =
U-Boot> fdt get value myvar /soc/gpio@7e200000 phandle; printenv myvar
myvar=0x0D000000Fix this by always treating the pointer as BE and converting it in
fdt_value_setenv(), like its counterpart fdt_parse_prop() already does.Consistently use fdt32_t, fdt32_to_cpu() and cpu_to_fdt32().

There are lots of reason why a FDT application might fail, the

The fdt_overlay_apply() function purports to support the edge cases where
an overlay has no fixups to be applied, or a base tree which has no
symbols (the latter can only work if the former is also true). However it
gets it wrong in a couple of small ways:* In the no fixups case, it doesn't fail immediately, but will attempt
fdt_for_each_property_offset() giving -FDT_ERR_NOTFOUND as the node
offset, which will fail. Instead it should succeed immediately, since
there's nothing to do.
* In the case of no symbols, it again doesn't fail immediately. However
if there is an actual fixup it will fail with an unexpected error,
because -FDT_ERR_NOTFOUND is passed to fdt_getprop() when attempting to
look up the symbols. We should instead return -FDT_ERR_NOTFOUND
directly.Both of these errors lead to the code returning misleading error codes in
failing cases.[ DTC commit: 7d8ef6e1db9794f72805a0855f4f7f12fadd03d3 ]

Until recently, sdhci_ops was used only for overriding IO accessors.
(so, host->ops was not set by any drivers except bcm2835_sdhci.c)Now, we have more optional callbacks, get_cd, set_control_reg, and
set_clock. However, the codeif (host->ops->get_cd)
host->ops->get_cd(host);... expects host->ops is set for all drivers.
Commit 5e96217f0434 ("mmc: pic32_sdhci: move the code to
pic32_sdhci.c") and commit 62226b68631b ("mmc: sdhci: move the
callback function into sdhci_ops") added sdhci_ops for pic32_sdhci.c
and s5p_sdhci.c, but the other drivers still do not (need not) set
host->ops because all callbacks in sdhci_ops are optional.host->ops must be checked to avoid the system crash caused by NULL
pointer access.Signed-off-by: Masahiro Yamada
