This change is largely based on existing eMMC framework by Haojian Zhuang
(@hzhuang1).
The MMC framework supports both eMMC and SD card devices. It was
written as a new framework since breaking few eMMC framework APIs.
At card probe and after the reset to idle command (CMD0), a Send
Interface Condition Command is sent (CMD8) to distinguish between
eMMC and SD card devices. eMMC devices go through the same
sequence as in the former eMMC framework. Else the framework
uses commands dedicated to SD-cards for init or frequency switch.
A structure is created to share info with the driver. It stores:
- the MMC type (eMMC, SD or SD HC)
- the device size
- the max frequency supported by the device
- the block size: 512 for eMMC and SD-HC and read from CSD
structure for older SD-cards
Restriction to align buffers on block size has been removed.
Cache maintenance was removed and is expected to be done in the platform
or device driver.
The MMC framework includes some MISRA compliance coding style
maybe not yet ported in the existing eMMC framework.

In the multi console driver, allowing to register the same console more
than once may result in an infinte loop when putc is called.
If, for example, a boot message is trying to be printed, but the
consoles in the loop in the linked list are runtime consoles, putc will
iterate forever looking for a console that can print boot messages (or
a NULL pointer that will never come).
This loop in the linked list can occur after restoring the system from a
system suspend. The boot console is registered during the cold boot in
BL31, but the runtime console is registered even in the warm boot path.
Consoles are always added to the start of the linked list when they are
registered, so this it what should happen if they were actually
different structures:
console_list -> NULL
console_list -> BOOT -> NULL
console_list -> RUNTIME -> BOOT -> NULL
console_list -> RUNTIME -> RUNTIME -> BOOT -> NULL
In practice, the two runtime consoles are the same one, so they create
this loop:
console_list -> RUNTIME -. X -> BOOT -> NULL
^ |
`----'
This patch adds an assertion to detect this problem. The assertion will
fail whenever the same structure tries to be registered while being on
the list.
In order to assert this, console_is_registered() has been implemented.
It returns 1 if the specified console is registered, 0 if not.

Accessing the interrupt_props array only happens inside a loop over
interrupt_props_num, so the GICv3 driver can cope with no secure
interrupts. This allows us to relax the asserts that insists on
a non-NULL interrupt_props pointer and at least one secure interrupt.
This enables GICv3 platforms which have no need for a secure interrupt.
This only covers the non-deprecated code paths.

Emit runtime warnings when intializing the GIC drivers using the
deprecated method of defining integer interrupt arrays in the GIC driver
data structures; interrupt_prop_t arrays should be used instead. This
helps platforms detect that they have migration work to do. Previously,
no warning was emitted in this case. This affects both the GICv2 and GICv3
drivers.
Also use the __deprecated attribute to emit a build time warning if these
deprecated fields are used. These warnings are suppressed in the GIC
driver compatibility functions but will be visible if platforms use them.

For platforms that have not migrated to MULTI_CONSOLE_API == 1, there
are a lot of confusing deprecated declaration warnings relating to
use of console_init() and console_uninit(). Some of these relate to use
by the generic code, not the platform code. These functions are not really
deprecated but *removed* when MULTI_CONSOLE_API == 1.
This patch consolidates these warnings into a single preprocessor warning.
The __deprecated attribute is removed from the console_init() and
console_uninit() declarations.
For preprocessor warnings like this to not cause fatal build errors,
this patch adds -Wno-error=cpp to the build flags when
ERROR_DEPRECATED == 0.
This option (and -Wno-error=deprecated-declarations) is now added to
CPPFLAGS instead of TF_CFLAGS to ensure the build flags are used in the
assembler as well as the compiler.
This patch also disentangles the MULTI_CONSOLE_API and ERROR_DEPRECATED
build flags by defaulting MULTI_CONSOLE_API to 0 instead of
ERROR_DEPRECATED. This allows platforms that have not migrated to
MULTI_CONSOLE_API to use ERROR_DEPRECATED == 1 to emit a more meaningful
build error.
Finally, this patch bans use of MULTI_CONSOLE_API == 1 and AARCH32, since
the AArch32 console implementation does not support
MULTI_CONSOLE_API == 1.

Delay functions like udelay() are often used to ensure that the
necessary time passed to allow some asynchronous event to finish, such
as the stabilization delay for a power rail. For these use cases it is
not very problematic if the delay is slightly longer than requested,
but it is critical that the delay must never be shorter.
The current udelay() implementation contains two hazards that may cause
the delay to be slightly shorter than intended: Firstly, the amount of
ticks to wait is calculated with an integer division, which may cut off
the last fraction of ticks needed. Secondly, the delay may be short by a
fraction of a tick because we do not know whether the initial ("start")
sample of the timer was near the start or near the end of the current
tick. Thus, if the code intends to wait for one tick, it might read the
timer value close to the end of the current tick and then read it again
right after the start of the next tick, concluding that the duration of
a full tick has passed when it in fact was just a fraction of it.
This patch rounds up the division and always adds one extra tick to
counteract both problems and ensure that delays will always be larger
but never smaller than requested.
