The System Cache (outer cache) is used not only as L2 cache,
but also as locked SRAM. The functions for turning on/off it
is necessary whether the L2 cache is enabled or not.
As the sLD3 Boot ROM has a complex page table, it is difficult to
set up the debug UART with enabling it. It will be much easier to
initialize the UART port after switching over to the straight-mapped
page table.

The meaning of CONFIG_USB in U-Boot is different from that in Linux.
As you see in drivers/usb/Kconfig of Linux, CONFIG_USB enables the
USB host controller support, while CONFIG_USB_SUPPORT is used to
enable the whole of the USB sub-system.
When I added CONFIG_USB into Kconfig by commit 6e7e9294d321 ("usb:
add basic USB configs in Kconfig"), I planned to follow the Linux's
convention, i.e. CONFIG_USB to enable/disable the USB host support.
Then, commit 68f7c5db2d1e ("usb: Generic USB Kconfig option, that
fits both host and gadget and comments") changed the logic of the
CONFIG_USB to point to the whole of the USB sub-system. As a result,
currently we do not have an option for USB host.
This commit adds CONFIG_USB_HOST, which will be useful to compile
in the USB host support code.
CONFIG_USB_HOST is not referenced at all, but strangely some boards
define it in board headers. I removed them because USB_HOST will be
selected in Kconfig going forward.
There is no UHCI driver entry in Kconfig for now, but we have some
UHCI drivers, for example, LEON. This is a placeholder in case we
want to move them to Kconfig in the future.
Add this option as a common config for all OHCI controllers. Its
help message was copied from Linux. Also, I moved it below EHCI
to respect the order in Linux's Kconfig.
Add CONFIG_USB_OHCI_HCD=y to axs103_defconfig, which is the only
user of OHCI_GENERIC.

We need to ensure that CONFIG_PHYS_64BIT is configured via Kconfig so
that it is always available to the build system. Otherwise we can run
into cases where we have inconsistent sizes of certain attributes.
Ravi Babu reported offset mismatch of struct dwc3 across files since
commit 95ebc253e6d4 ("types.h: move and redefine resource_size_t").
Since the commit, resource_addr_t points to phys_addr_t, whose size
is dependent on CONFIG_PHYS_64BIT for ARM architecture.
I tried my best to use "select" where possible (for example, ARMv8
architecture) because I think this kind of option is generally user-
unconfigurable. However, I see some of PowerPC boards have 36BIT
defconfigs as well as 32BIT ones. I moved CONFIG_PHYS_64BIT to the
defconfigs for such boards.
CONFIG_36BIT is no longer referenced, so all of the defines were

The tools/moveconfig.py has a feature to cleanup #define/#undef's
of moved config options, but I want this tool to do a better job.
For example, when we are moving CONFIG_FOO and its define is
surrounded by #ifdef ... #endif, like follows:
#ifdef CONFIG_BAR
# define CONFIG_FOO
#endif
The header cleanup will leave empty #ifdef ... #endif:
#ifdef CONFIG_BAR
#endif
Likewise, if a define line between two blank lines
<blank line>
#define CONFIG_FOO
<blank lines.
... is deleted, the result of the clean-up will be successive empty
lines, which is a coding-style violation.
It is tedious to remove left-over garbage lines manually, so I want
the tool to take care of this. The tool's job is still not perfect,
so we should check the output of the tool, but I hope our life will
be much easier with this patch.
