Subject: [PATCH 1/2] crypto: crypto4xx - reduce memory fragmentation
To: linux-crypto@vger.kernel.org
Cc: Herbert Xu <herbert@gondor.apana.org.au>
With recent kernels (>5.2), the driver fails to probe, as the
allocation of the driver's scatter buffer fails with -ENOMEM.
This happens in crypto4xx_build_sdr(). Where the driver tries
to get 512KiB (=PPC4XX_SD_BUFFER_SIZE * PPC4XX_NUM_SD) of
continuous memory. This big chunk is by design, since the driver
uses this circumstance in the crypto4xx_copy_pkt_to_dst() to
its advantage:
"all scatter-buffers are all neatly organized in one big
continuous ringbuffer; So scatterwalk_map_and_copy() can be
instructed to copy a range of buffers in one go."
The PowerPC arch does not have support for DMA_CMA. Hence,
this patch reorganizes the order in which the memory
allocations are done. Since the driver itself is responsible
for some of the issues.

Subject: [PATCH 2/2] crypto: crypto4xx - use GFP_KERNEL for big allocations
To: linux-crypto@vger.kernel.org
Cc: Herbert Xu <herbert@gondor.apana.org.au>
The driver should use GFP_KERNEL for the bigger allocation
during the driver's crypto4xx_probe() and not GFP_ATOMIC in
my opinion.

Subject: [PATCH] powerpc: bootwrapper: force gzip as mkimage's compression
method
Due to CONFIG_KERNEL_XZ symbol, the bootwrapper code tries to
instruct the mkimage to use the xz compression, which isn't
supported. This patch forces the gzip compression, which is
supported and doesn't matter because the generated uImage for
the apm821xx target gets ignored as the OpenWrt toolchain will
do separate U-Boot kernel images for each device individually.
