crypto: ccree - remove struct cc_sram_ctx

2020-02-22T01:25:44Z

The cc_sram_ctx structure contains only a single member, and only one instance exists. Simplify the code and reduce memory consumption by moving this member to struct cc_drvdata. Signed-off-by: Geert Uytterhoeven Signed-off-by: Herbert Xu

crypto: ccree - use u32 for SRAM addresses

2020-02-22T01:25:44Z

SRAM addresses are small integer offsets into local SRAM. Currently they are stored using a mixture of cc_sram_addr_t (u64), u32, and dma_addr_t types. Settle on u32, and remove the cc_sram_addr_t typedefs. This allows to drop several casts. Signed-off-by: Geert Uytterhoeven Signed-off-by: Herbert Xu

crypto: ccree - remove bogus paragraph about freeing SRAM

2020-02-22T01:25:44Z

The SRAM allocator does not support deallocating memory. Hence remove all references to freeing SRAM. Fix grammar while at it. Signed-off-by: Geert Uytterhoeven Signed-off-by: Herbert Xu

crypto: ccree - remove empty cc_sram_mgr_fini()

2020-02-22T01:25:43Z

cc_sram_mgr_fini() doesn't do anything, so it can just be removed. Signed-off-by: Geert Uytterhoeven Signed-off-by: Herbert Xu

crypto: ccree - copyright header update

2019-04-25T07:38:14Z

This sacrificial copyright header update is offered to the legal department as atonement for any changes made in this driver files in the course of the current year which have not been duly recorded as such. Signed-off-by: Gilad Ben-Yossef Signed-off-by: Herbert Xu

crypto: ccree - use devm_kzalloc for device data

2019-04-25T07:38:14Z

Move some remaining device data allocation to the safer devm_* interface. Signed-off-by: Gilad Ben-Yossef Signed-off-by: Herbert Xu

crypto: ccree - add support for older HW revs

2018-03-02T16:03:16Z

Add support for the legacy CryptoCell 630 and 710 revs. Signed-off-by: Gilad Ben-Yossef Signed-off-by: Herbert Xu

crypto: ccree - introduce CryptoCell driver

2018-02-15T15:26:40Z

Introduce basic low level Arm TrustZone CryptoCell HW support. This first patch doesn't actually register any Crypto API transformations, these will follow up in the next patch. This first revision supports the CC 712 REE component. Signed-off-by: Gilad Ben-Yossef Signed-off-by: Herbert Xu
