powerpc/t4240: Adding workaround errata A-005871
When CoreNet Fabric (CCF) internal resources are consumed by the cores,
inbound SRIO messaging traffic through RMan can put the device into a
deadlock condition.
This errata workaround forces internal resources to be reserved for
upstream transactions. This ensures resources exist on the device for
upstream transactions and removes the deadlock condition.
The Workaround is for the T4240 silicon rev 1.0.

This can address the security risk of untrusted data being used during boot.
Any time you load untrusted data you expose yourself to a bug in the
code. The attacker gets to choose the data so can sometimes carefully
craft it to exploit a bug. We try to avoid touching user-controlled
data during a verified boot unless strictly necessary. Since the
default environment is good enough in this case (or you would just
change it), this gets around the problem by just not loading the
environment.
When CONFIG_DELAY_ENVIRONMENT is defined, it is convenient to have a
run-time way of enabling loading of the environment. Add this to the
fdt as /config/delay-environment.

arm: Move fdt check earlier so that board_early_init_f() can use it
We want to use the fdt inside board_early_init_f(), so check for its
presence earlier in the pre-reloc init sequence.
So far ARM and microblaze are the only only ones that use
CONFIG_OF_CONTROL. Microblaze does not have the same init loop, and in
particular does not have the board_early_init_f() call. So a patch for
microblaze would have no meaning.

arm: Keep track of the tlb size as well as its location
It may be necessary to know where the TLB area ends as well as where it
starts. This allows board code to complete a secure memory erase without

arm: move flush_dcache_all() to just before disable cache
In Cortex-A15 architecture, when we run cache invalidate
the cache clean operation executes automatically.
So if there are any dirty cache lines before disabling the L2 cache
these will be synchronized with the main memory when
invalidate_dcache_all() runs in the last part of U-boot
The two functions after flush_dcache_all is using the stack. So this
data will be on the cache. After disable when invalidate is called the
data will be flushed from cache to memory. This corrupts the stack in
invalida_dcache_all. So this change is required to avoid the u-boot
hang.
So flush has to be done just before clearing CR_C bit

cfi_flash: Enable PPB protection for all AMD cmdset flash chips
Not only Spansion supports the Persistent Protection Bits (PPB) locking.
Other devices like the Micron JS28F512M29EWx also support this type
of locking/unlocking. Detection of support is done in the same way as
done for the Spansion chips - via the 0x49 CFI word.
This patch enables this PPB protection mechanism for all AMD type
(AMD commandset) chips.

cfi_flash: Read PPB sector protection from device for AMD/Spansion chips
Patch 66863b05 [cfi_flash: add support for Spansion flash PPB sector
protection] introduced the PPB (Persistent Protection Bit) locking for
Spansion chips. But right now the sector protection status (locked vs
unlocked) is set to unlocked for all sectors upon bootup. The real
sector protection status is ignored.
This patch now reads the current sector protection status and uses
it for these AMD/Spansion flash chips.
mtd/cfi: add support for SST 4KB sector granularity
Add support for SST 4KB sector granularity.
Many recent SST flashes, i.e. SST39VF3201B and similar of this family
are declared CFI-conformant from SST. They support CFI query, but implement
2 different sector sizes in the same memory: a 64KB sector (they call it
"block", std AMD erase cmd=0x30), and a 4KB sector (they call it "sector",
erase cmd=0x50). Also, CFI query on these chips, reading from address 0x2dh
of cfi query struct, detects a number of secotrs for the 4KB granularity
(flinfo shows it).
For all other aspects, they are CFI compliant, so, as Linux do, i think
it's a good idea to handle these chips in the CFI driver, with a fixup
to allow 4KB granularity, as should be expected, instead of 64KB.

video: Modify exynos_fimd driver to support LCD console
Currently, exynos FIMD driver is being used to support only TIZEN LOGOs.
In order to get LCD console, we need to enable half word swap feature
of FIMD and use 16 BPP.
LCD console and proprietary Logo cannot be used simultaneously.
We use "logo_on" field inside vidinfo_t structure to decide whether
user wants Logo or Console.
Define CONFIG_CMD_BMP and make logo_on = 1 to get Logo on screen.
Use logo_on = 0 to get output console on LCD.
