A large number of drivers "depends on" SPI_MEM but this is library type
functionality and so must be select'd instead in order to ensure that
drivers will build. Correct this usage and hide the symbol normally.

Tom Rini <[email protected]> says:
As seen by a number of patches fixing memory leaks, U-Boot has a problem
with developer expectations around devm_kmalloc and friends. Namely,
whereas in Linux these memory allocations will be freed automatically in
most cases, in U-Boot this is only true if DEVRES is enabled. Now,
intentionally, in xPL phases, we do not (and do not offer as an option)
enabling DEVRES. However in full U-Boot this is left either to the user,
or some drivers have select'd DEVRES on their own. This inconsistency is
a problem. This series goes and deals with two small issues that were
shown by having all drivers that use devm_.alloc to allocate memory also
select DEVRES and then we make DEVRES no longer be a prompted option and
instead select'd as needed. We do not make this unconditional as it
would result in growing the resulting binary on the many platforms which
have no users of the devm_.alloc family of functions.

The devm alloc functions that we have may follow the Linux kernel model
where allocations are (almost always) automatically free()'d. However,
quite often we don't enable, in full U-Boot, the tracking and free()'ing
functionality. This in turn leads to memory leaks because the driver
author expects that since the functions have the same name as in the
Linux Kernel they have the same behavior. In turn we then get
functionally correct commits such as commit 00e1fed93c8c ("firmware:
ti_sci: Fix memory leaks in devm_ti_sci_get_of_resource") that manually
add these calls. Rather than manually tracking allocations and
implementing free()s, rework things so that we follow expectations by
enabling the DEVRES functionality (outside of xPL phases).
This turns DEVRES from a prompted symbol to a symbol that must be
select'd, and we now remove our non-managed alloc/free functions from
outside of xPL builds.

This patch ports the Cadence xSPI controller driver from
the Linux kernel. The controller supports three operating modes:
1. ACMD (Auto Command) mode
- Includes PIO and CDMA submodes.
- CDMA mode uses linked descriptors for high-performance,
low-overhead operation.
- PIO mode is suitable for simple, single-command transactions.
2. STIG (Software Triggered Instruction Generator) mode
- Issues low-level 128-bit instructions to memory.
- Uses the Slave DMA interface for data transfers.
3. Direct mode
- Enables direct data access through the slave interface
without commands.
Currently, only the STIG work mode is enabled. Additional modes will be
supported in future updates.
At the same time, also enabling the kconfig option for xSPI driver.
This driver has been ported and functionally verified on the Intel Simics
platform. It is intended for evaluation and experimental use at this stage.

In parallel mode, the current implementation assumes that a maximum of
two flashes are connected. The QSPI controller splits the data evenly
between both the flashes so, both the flashes that are connected in
parallel mode should be identical.
During each operation SPI-NOR sets 0th bit for CS0 & 1st bit for CS1 in
nor->flags.
In stacked mode the current implementation assumes that a maximum of two
flashes are connected and both the flashes are of same make but can
differ in sizes. So, except the sizes all other flash parameters of both
the flashes are identical
Spi-nor will pass on the appropriate flash select flag to low level
driver, and it will select pass all the data to that particular flash.
Write operation in parallel mode are performed in page size * 2 chunks as
each write operation results in writing both the flashes. For doubling
the address space each operation is performed at addr/2 flash offset,
where addr is the address specified by the user.
Similarly for read and erase operations it will read from both flashes,
so size and offset are divided by 2 and send to flash.
Adding the config option SPI_ADVANCE for non SPL code.

Add ASPEED BMC FMC/SPI memory controller driver with
spi-mem interface for AST2500 and AST2600 platform.
There are three SPI memory controllers embedded in an ASPEED SoC.
- FMC: Named as Firmware Memory Controller. After AC on, MCU ROM
fetches initial device boot image from FMC chip select(CS) 0.
- SPI1: Play the role of a SPI Master controller. Or, there is a
dedicated path for HOST(X86) to access its BIOS flash mounted
under BMC. spi-aspeed-smc.c implements the control sequence when
SPI1 is a SPI master.
- SPI2: It is a pure SPI flash controller. For most scenarios, flashes
mounted under it are for pure storage purpose.
ASPEED SPI controller supports 1-1-1, 1-1-2 and 1-1-4 SPI flash mode.
Three types of command mode are supported, normal mode, command
read/write mode and user mode.
- Normal mode: Default mode. After power on, normal read command 03h or
13h is used to fetch boot image from SPI flash.
- AST2500: Only 03h command can be used after power on
or reset.
- AST2600: If FMC04[6:4] is set, 13h command is used,
otherwise, 03h command.
The address length is decided by FMC04[2:0].
- Command mode: SPI controller can send command and address
automatically when CPU read/write the related remapped
or decoded address area. The command used by this mode
can be configured by FMC10/14/18[23:16]. Also, the
address length is decided by FMC04[2:0]. This mode will
be implemented in the following patch series.
- User mode: It is a traditional and pure SPI operation, where
SPI transmission is controlled by CPU. It is the main
mode in this patch.
Each SPI controller in ASPEED SoC has its own decoded address mapping.
Within each SPI controller decoded address, driver can assign a specific
address region for each CS of a SPI controller. The decoded address
cannot overlap to each other. With normal mode and command mode, the
decoded address accessed by the CPU determines which CS is active.
When user mode is adopted, the CS decoded address is a FIFO, CPU can
send/receive any SPI transmission by accessing the related decoded
address for the target CS.
This patch only implements user mode initially. Command read/write
mode will be implemented in the following patches.
