hi3516av300_neo: add modern (Linux 7.0+) firmware variant#2023
Conversation
Picks up openhisilicon#59: EXPORT_SYMBOL for ssp_drv_init/exit/get_ops in CV300 sensor_spi, fixing split sensor module dependencies. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Add a "neo" variant for the hi3516av300 board running OpenIPC on the upstream-patches kernel branch (Linux 7.0+) instead of the vendor 4.9.37 kernel. Per OpenIPC/openhisilicon#51, the CV500 platform has zero direct kernel API calls in blobs — everything goes through OSAL, making it a top-priority candidate for kernel modernization. New files: - br-ext-chip-hisilicon/configs/hi3516av300_neo_defconfig Buildroot defconfig with glibc toolchain, 16MB flash, upstream-patches kernel, BR2_OPENIPC_VARIANT="neo". - br-ext-chip-hisilicon/board/hi3516cv500/hi3516av300.neo.config Seed kernel config with ARCH_HI3516DV300, COMMON_CLK_HI3516DV300, earlycon at 0x120a0000, ZRELADDR=0x80008000, CMA, MTD/SPI-NOR. Aggressive size trimming (no IPv6, no NETFILTER, no input/sound/USB, no JFFS2/CRAMFS/loop/RAM block) keeps uImage under 2048KB limit. - br-ext-chip-hisilicon/board/hi3516cv500/neo-post-image.sh Concatenates zImage + DTB and wraps as uImage (load 0x80008000). Modified packages: - hisilicon-opensdk.mk: Replace 6 hardcoded kernel versions (3.0.8/3.18.20/4.9.37) with dynamic `kernel.release` detection, bump to OpenIPC/openhisilicon#61 commit (Linux 5.0-7.0 compat). - hisilicon-osdrv-hi3516cv500.mk: Same dynamic kernel version. - load_hisilicon: `uname -r` instead of hardcoded 4.9.37. Tested: - QEMU: U-Boot → Linux 7.0 → squashfs rootfs from MTD → login - Real hardware (hi3516av300/MX25L256 32MB flash): builds and flashes via sysupgrade Companion changes: - openipc/linux upstream-patches: ARCH_HI3516DV300 DTS, CV500/DV300 clock drivers, mach machine descriptor - OpenIPC/openhisilicon#61: Linux 5.0-7.0 OSAL compat - widgetii/qemu-hisilicon#33: CV500 SMP + flash boot Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Summary
New `hi3516av300_neo` firmware variant — runs OpenIPC on Linux 7.0+ (upstream-patches branch) instead of vendor 4.9.37, following the `hi3516ev300_neo` pattern.
Per OpenIPC/openhisilicon#51, CV500 has zero direct kernel API calls in blobs — everything goes through OSAL — making it a top-priority candidate for kernel modernization.
