Subject: fsl-ch3/lowlevel: TZPC and TZASC programming to configure non-secure
 accesses

This patch ensures that the TZPC (BP147) and TZASC-400 programming
happens for LS2085A SoC only when the desired config flags are
enabled and ensures that the TZPC programming is done to allow Non-secure
(NS) + secure (S) transactions only for DCGF registers.

The TZASC component is not present on LS2085A-Rev1, so the TZASC-400
config flag is turned OFF for now.

+Freescale ARM64 SoCs like LS2085A have ARM TrustZone components like
+TZPC-BP147 (TrustZone Protection Controller) and TZASC-400 (TrustZone
+Address Space Controller).
+
+While most of the configuration related programming of these peripherals
+is left to a root-of-trust security software layer (running in EL3
+privilege mode), but still some configurations of these peripherals
+might be required while the bootloader is executing in EL3 privilege
+mode. The following sections define how to turn on these features for
+LS2085A like SoCs.
+
+TZPC-BP147 (TrustZone Protection Controller)
+============================================
+- Depends on CONFIG_FSL_TZPC_BP147 configuration flag.
+- Separates Secure World and Normal World on-chip RAM (OCRAM) spaces.
+- Provides a programming model to set access control policy via the TZPC
+  TZDECPROT Registers.
+
+TZASC-400 (TrustZone Address Space Controller)
+==============================================
+- Depends on CONFIG_FSL_TZASC_400 configuration flag.
+- Separates Secure World and Normal World external memory spaces for bus masters
+  such as processors and DMA-equipped peripherals.
+- Supports 8 fully programmable address regions, initially inactive at reset,
+  and one base region, always active, that covers the remaining address space.

Subject: armv8/fsl-lsch3: Convert flushing L3 to assembly to avoid using stack

Flushing L3 cache in CCN-504 requries d-cache to be disabled. Using
assembly function to guarantee stack is not used before flushing is
completed. Timeout is needed for simualtor on which CCN-504 is not
implemented. Return value can be checked for timeout situation.

Change bootm.c to disable dcache instead of simply flushing, required
by flushing L3.

FSL-LSCH3 platforms can have multiple DDR clocks. LS2085A has one clock for
general DDR controlers, and another clock for DP-DDR. DDR driver needs to
change to support multiple clocks.

From 03e664d8f4065010ccb6c75648192200a832fd8b Mon Sep 17 00:00:00 2001
From: York Sun <yorksun@freescale.com>
Date: Tue, 6 Jan 2015 13:18:50 -0800
Subject: driver/ddr/fsl: Add support for multiple DDR clocks

Controller number is passed for function calls to support individual
DDR clock, depending on SoC implementation. It is backward compatible
with exising platforms. Multiple clocks have been verifyed on LS2085A
emulator.

Subject: arm/ls102xa: create TLB to map PCIe region

LS1021A's PCIe1 region begins 0x40_00000000; PCIe2 begins
0x48_00000000. In order to access PCIe device, we must create
TLB to map the 40bit physical address to 32bit virtual address.
This patch will enable MMU after DDR is available and creates MMU
table in DRAM to map all 4G space; then, re-use the reserved space
to map PCIe region. The following the mapping layout.

VA mapping:
    -------  <---- 0GB
   |       |
   |       |
   |-------| <---- 0x24000000
   |///////|  ===> 192MB VA map for PCIe1 with offset 0x40_0000_0000
   |-------| <---- 0x300000000
   |       |
   |-------| <---- 0x34000000
   |///////|  ===> 192MB VA map for PCIe2 with offset 0x48_0000_0000
   |-------| <---- 0x40000000
   |       |
   |-------| <---- 0x80000000 DDR0 space start
   |\\\\\\\|
   |\\\\\\\|  ===> 2GB VA map for 2GB DDR0 Memory space
   |\\\\\\\|
   -------  <---- 4GB DDR0 space end

Subject: arm: ls102xa: workaround for cache coherency problem

The RCPM FSM may not be reset after power-on, for example,
in the cases of cold boot and wakeup from deep sleep.
It causes cache coherency problem and may block deep sleep.
Therefore, reset them if they are not be reset.

Subject: crypto/fsl: Make function names consistent for blob
 encapsulation/decapsulation.

This patch does the following:

1. The function names for encapsulation and decapsulation
were inconsitent in freescale's implementation and cmd_blob file.
This patch corrects the issues.
2. The function protopye is also modified to change the length parameter
from u8 to u32 to allow encapsulation and decapsulation of larger images.
3. Modified the description of km paramter in the command usage for better
readability.
