      memory: atmel-ebi: make it explicitly non-modular · 8a86a093
      由 Paul Gortmaker 提交于 
      The Kconfig currently controlling compilation of this code is:

drivers/memory/Kconfig:config ATMEL_EBI
drivers/memory/Kconfig: bool "Atmel EBI driver"

...meaning that it currently is not being built as a module by anyone.

Lets remove the few remaining modular references, so that when reading
the driver there is no doubt it is builtin-only.

Since module_platform_driver() uses the same init level priority as
builtin_platform_driver() the init ordering remains unchanged with
this commit.

Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.

We also delete the MODULE_LICENSE tag etc. since all that information
is already contained at the top of the file in the comments.

      memory: atmel-sdramc: make it explicitly non-modular · 563b41c9
      由 Paul Gortmaker 提交于 
      The Kconfig for this option is currently:

config ATMEL_SDRAMC
        bool "Atmel (Multi-port DDR-)SDRAM Controller"

...meaning that it currently is not being built as a module by anyone.
Lets remove the couple traces of modularity, so that when reading the
driver there is no doubt it is builtin-only.

Since module_init translates to device_initcall in the non-modular
case, the init ordering remains unchanged with this commit.  An
alternate init level might be worth considering at a later date.

Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.

We also delete the MODULE_LICENSE tag etc. since all that information
was (or is now) contained at the top of the file in the comments.

      memory/mediatek: add support for mt2701 · 3c8f4ad8
      由 Honghui Zhang 提交于 
      Mediatek SMI has two generations of HW architecture, mt8173 uses the
second generation of SMI HW while mt2701 uses the first generation
HW of SMI.

There's slight differences between the two generations, for generation 2,
the register which control the iommu port access PA or IOVA is at each
larb's register base. But for generation 1, the register is at smi ao
base(smi always on register base).
Besides that, the smi async clock should be prepared and enabled for SMI
generation 1 HW to transform the smi clock into emi clock domain, but is
not needed for SMI generation 2.

This patch add SMI driver for mt2701 which use generation 1 SMI HW.

      memory: samsung: exynos-srom: make it explicitly non-modular · 58f388bc
      由 Paul Gortmaker 提交于 
      The Kconfig currently controlling compilation of this code is:

memory/samsung/Kconfig:config EXYNOS_SROM
memory/samsung/Kconfig: bool "Exynos SROM controller driver" if COMPILE_TEST

...meaning that it currently is not being built as a module by anyone.

Lets remove the modular code that is essentially orphaned, so that
when reading the driver there is no doubt it is builtin-only.

We explicitly disallow a driver unbind, since that doesn't have a
sensible use case anyway, and it allows us to drop the ".remove"
code for non-modular drivers.

Since module_platform_driver() uses the same init level priority as
builtin_platform_driver() the init ordering remains unchanged with
this commit.

Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.

We also delete the MODULE_LICENSE tag etc. since all that information
is already contained at the top of the file in the comments.

We don't replace module.h with init.h since the file already has that.

      memory: omap-gpmc: Fix omap gpmc EXTRADELAY timing · 8f50b8e5
      由 Ocquidant, Sebastien 提交于 
      In the omap gpmc driver it can be noticed that GPMC_CONFIG4_OEEXTRADELAY
is overwritten by the WEEXTRADELAY value from the device tree and
GPMC_CONFIG4_WEEXTRADELAY is not updated by the value from the device
tree.

As a consequence, the memory accesses cannot be configured properly when
the extra delay are needed for OE and WE.

Fix the update of GPMC_CONFIG4_WEEXTRADELAY with the value from the
device tree file and prevents GPMC_CONFIG4_OEXTRADELAY
being overwritten by the WEXTRADELAY value from the device tree.

      fsl-ifc: add missing include on ARM64 · c4aa1937
      由 Lijun Pan 提交于 
      Need to include sched.h to fix the following compilation error
if FSL_IFC is enabled on ARM64 machine.

In file included from include/linux/mmzone.h:9:0,
                 from include/linux/gfp.h:5,
                 from include/linux/kmod.h:22,
                 from include/linux/module.h:13,
                 from drivers/memory/fsl_ifc.c:22:

drivers/memory/fsl_ifc.c:136:3: note: in expansion of macro ‘wake_up’
   wake_up(&ctrl->nand_wait);
   ^

Analysis is as follows:
I put some instrumental code and get the
following .h files inclusion sequence:

In file included from ./arch/arm64/include/asm/compat.h:25:0,
                 from ./arch/arm64/include/asm/stat.h:23,
                 from include/linux/stat.h:5,
                 from include/linux/module.h:10,
                 from drivers/memory/fsl_ifc.c:23:
include/linux/sched.h:113:1: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘struct’
 struct sched_attr {
 ^

CONFIG_COMPAT=y is enabled while 39 and 48 bit VA is selected.
When 42 bit VA is selected, it does not enable CONFIG_COMPAT=y

In ./arch/arm64/include/asm/stat.h:23, it has
"#ifdef CONFIG_COMPAT"
"#include <asm/compat.h>"
"..."
"#endif"

Since ./arch/arm64/include/asm/stat.h does not
include ./arch/arm64/include/asm/compat.h,
then it will not include include/linux/sched.h
Hence we have to manually add "#include <linux/sched.h>"
in drivers/memory/fsl_ifc.c

      memory: pl172: add ARM PrimeCell PL176 MPMC support · f6d77bee
      由 Vladimir Zapolskiy 提交于 
      The change adds support of ARM PrimeCell PL176 MPMC.

Static memory configuration of PL175 MPMC is very similar to one found
on PL172 and PL175 controllers, so it is preferred to add its support
into the existing driver. The difference is that PL176 supports up to
10 slave ports (but only 4 of them may be connected to static memory
devices), AHB master bus width cab be 64-bit wide, also NAND devices
can be interfaced.

Similar to PL175 contoller, PL176 has no write buffer enable control
in static memory configuration register, the rest of static memory
configuration bits (with exception of NAND) is the same.

      memory: pl172: add ARM PrimeCell PL175 MPMC support · b794df56
      由 Vladimir Zapolskiy 提交于 
      The change adds support of ARM PrimeCell PL175 MPMC, the controller is
found on NXP LPC32xx SoC.

PL175 MPMC is very similar to PL172 controller, so it is preferred to
add its support into the existing driver.

One of the differences between PL172 and PL175 is that the latter one
supports up to 6 AHB ports, but still only 4 AHB ports can be assigned
to a static memory device, also PL175 does not have write buffer
enable control in static memory configuration register.
