e09a5efcdb ipq40xx: 5.4: enable NAND
Lets enable RAW NAND and Qcom NANDC drivers again in kernel 5.4.
They were dropped when 5.4 support was introduced due to upstream
changing the symbol names so refreshing was not enough.

4ff6c43499 ipq40xx: add IPQ4019 SD/MMC controller support
This commit finally adds support for the built in SD/MMC controller in IPQ4019 SoC.

Controller is supported by the upstream SDHCI-MSM driver with a minor clock setting patch.
Patch is special to the IPQ4019 and cannot be upstreamed.

LDO and SDHCI node are upstreamed, and LDO node is awaiting to be accepted.

91a7c9c27d ipq40xx: 5.4: refresh patches and config
This patch just refreshes the 5.4 patches. It seems as if
070-v4.20-soc-qcom-spm-add-SCM-probe-dependency.patch is
already applied, so drop it. It also does a quick
make kernel_oldconfig to get rid of unneeded symbols.

[Looks like USB and Ethernet need some more work].

ee4a0afdcd ipq40xx: use neon crypto drivers
This adds the neon based implementations of AES & SHA256.

For AES, according to the kernel config help:

Use a faster and more secure NEON based implementation of AES in CBC,
CTR and XTS modes.
Bit sliced AES gives around 45% speedup on Cortex-A15 for CTR mode
and for XTS mode encryption, CBC and XTS mode decryption speedup is
around 25%. (CBC encryption speed is not affected by this driver.)
This implementation does not rely on any lookup tables so it is
believed to be invulnerable to cache timing attacks.
...
The observed speedups on ipq40xx are more modest: speedup is around 20%
for CTR mode and for XTS mode encryption, CBC and XTS mode decryption
speedup is around 10%. Measurements were made using tcrypt, with
1024-bytes blocks for CTR & CBC, and 4096-bytes for XTS.
The aes-neon-bs driver uses a fallback for CBC encryption; that fallback
could be either the generic driver written in C, or the scalar arm-asm
one.  Even though aes-arm is 1.9% slower, it is more resilient to timing
attacks (the reason for being slower), so it is being included here.

The neon sha256 module increases performance over the generic module by
33%.
